thanks mate
thanks boss!
legend 👑
thank you
THANK YOU SO MUCH!!!
man u know what? i usually don't make a comment but, seriously, u r awesome talented teacher
Oh
yes ooo. he really tried by explaining in bit
yes he is thank you man
He knows everything. He's all-rounder
Agreed
Man, its not even worth it to attend 3 weeks of physics lectures anymore. This video taught me better in 1 hour, absolutely talented individual, tysm
I go to a private university here in Egypt, and pay huge amounts of money for tuition yet, I get not even 50 percent of the teaching you provide. Thank you for always making every subject as easy and understandable as it could be. You are seriously awesome !!
so should i yeet out of applying to private unis?
This comment makes me sad
@@JM-uw5mo sad but happy, sad they cant teach like this, happy that as good of a teach like him exists
معلش يسطا, على الله
احيه
The money I pay in school, I should have been paying this man and even more. I don't attend classes regularly but do better than those always in class in chemistry, physics and maths. May God continue blessing you for saving lives.
honestly I should be paying this man several thousand a semester over my professors bc he teaches me way more and doesn’t judge me when I don’t understand how to do this lol
Am looking for a teacher that can really teach me mathematics honestly
I'm sorry, but it's illegal to be this smart in both chemistry and physics
And math also
At 5:30, there's an error. The arrow for the distance in magnetic field strength equation should be opposite.
I ^ = B ^
R *(down)* = B ^
Almost didn’t notice this
I was confused by that😂
yea i notice it too make me so confused.
I’m just looking for this comment 😂
yes I got so confused
You’re literally one of the best communicators, and have a real gift at explaining concepts, complicated or not, in such an easy to understand manner. You explain it so well, that is almost impossible to not understand it afterwards. I can’t thank you enough for all your indirect help from your videos. Especially allowing us to view them for free is the real kicker. You have a great mind and a big heart to put the time and effort into your playlists. I’m going to school for my BS in mechanical engineering, and you literally helped me get straight As through all the pre req engineering courses, Calc based chem1&2, Calc based Physics1&2, and Calc 1&2. Please keep up the great work!!!! You rock!
Only reason why I'm passing Physics 2
this is physics 3 where i go to school
Ain’t that truth lol
Facts lmao
Physics galaxy is best chanel for physics lover
Clorox Bleach me too, but I know some people that take electromagnetism/modern physics second year then take optics/pressure/laws of thermodynamics
For people like me, who can't understand something without understanding the basics first, the explanation with the X, Y and Z direction helped so much!
Yea me too
What an absolute MADLAD. This is almost everything we covered for this upcoming test. Couldn't pay attention in class but i'm getting a good grade now thanks to you! Love your video, will keep coming back.
Just passed physics thanks to this guy 🤘🏽
If my college didn't have an attendance policy, I would just skip class and watch this guy's videos
@@derpherpula592 Go the back of class, put on headphones, and watch his videos!
True
same here! :D
Same here sis🙌🏼🤟🏼
This man is getting me through an accelerated Engineering Physics 2 course. Seriously, you are a king among men. I wish all the blessings onto you, good sir.
Your videos are SO amazing! I used them for Orgo 1 & 2 & for Physics 1 & now for Physics 2! I don't know how I would learn everything without them! Thank you so much!
hi zoe

First 3 mins One of the Right-Hand Rule
15:30 Another Hand Rule
24:27 Hand Rule for a relatively difficult problem (changing direction of force)
31:00 Hand Rule with respect to velocity
Thank you for being better than my professors! Been watching these as well as your calc 2 videos to either brush up (or full on learn) the content that I need to know for my exams and tests. You've been a lifesaver and make them much easier to understand! Don't stop making the videos you're helping so many people! Just wanted to say thanks!!!!!
Low voice is the only problem, I even used subtitles for better clarity. ABOVE ALL, I THANK YOU MISTER.
Thanks
I have never been taking physics, and maths just because I was discouraged they are difficult and have never been passing them, now I'm in my last year in high school, when I came across his teachings, I discovered he makes everything simple, so I immediately registered physics and maths and with faith I'll pass them and very well. Thank you for directing me to the engineering field and above all thank God for having you. You are nothing but the best
This guy is worth his weight in gold honestly. You are just an amazing educator!! Thank you so much!!!!!!
Dude, I was able to finish my homework in less than 3 hours because of this video. You Rock!
Great video my friend I really like that you use such simple examples. It makes learning the equations and understanding the relationships between the variables quick and easy.
This one video sums up 2 weeks and 7 lectures for my physics class. 7 years later, THANK YOU!
When online physics is taught by a boomer
Go to the Organic Chemistry Tutor
@@octobersveryown29 fs, just wrote this in good fun when my physics teacher sped up the pace x10000
We are all just trying to learn what are elders and ancestors discovered. Try not to be too vain guys.
@@will808080 isajoke? Wdym vain i just felt like writing sum funny
@@kmn9568 The term “Boomer” is used to dismiss the older generation, meaning it is disrespectful. In this case it seems vain because physics formulas and books are written by our predecessors or “boomers”. Just trying to enlighten you since you asked. Enjoy.
@@will808080 we started to use the term boomer because we found it annoying when boomers flexed their boomerness to us about how "back in their day" kinda crap. I don't really need to be enlightened and I will use the term freely. In this case it is a joke I used to make a rhyme and I really don't see a reason why that's not a thing people would be ok with. It's the internet bud , if you weren't only subbed to every science channel you'd literally be spending your life correcting others rhetoric. Friendly advice, no one actually "enjoys" it and you will eventually get murdered with words. Enjoy
you are an awsome teacher.i hope God blesses you abundantly. you are the reason why many students actually pass and understand STEM modules.. keep up the good work and know that we appreciate your work!
I’m studying for the MCAT and couldn’t remember these concepts at all. You helped me relearn material I haven’t seen in over 6 years. THANK YOUUU so so much!!
Physics is rough but these legacy videos are coming in clutch. Thank you for the clarity and brevity.
Thank you so much for your explanation of magnetism. You explain the subject matter way better than my textbook.
Just learned an entire 3 weeks of content in 1 hour, thank you so much
the way the physic flow in you...simple and easy to understand you're gifted Man.
Up until this point I’ve only been using Flemmings Left Hand Motor Rule to determine the direction of force, magnetic field and current. The technique you showed here with the palm of your right hand is so much easier to use and remember. Thank you!
this is almost 2020
AND THIS VIDEO IS HUGELY HELPFUL
very glad you made this
You save me a lot of time
Love your videos, you ease alot of the anxiety that comes with learning these things with your well thought out explanations and train of thought that all flow very easily. Much thanks and appreciation from me!! :)
You are the best communicator and teacher I ever got, your way of explanation made me understand even what I failed to understand from my professor in 4 months. Thank you for being there for all of us. You deserve more, God bless you.. ✍️🙏🏼🙏🏼
I currently am a junior taking ap physics 1, and I plan on taking ap physics 2 next year. Your videos thoroughly explain this topic in a simplistic yet advanced way that anyone can understand. I plan to watch all your ap physics 2 videos before I take ap physics 2 so I can have a further understanding
your presentation is fabulous....you. clear my. confusing ....
Thank you hopefully this will help me on physic portion of the MCAT. I definitely feel more confident.
Can I just say, god bless u! You save me in every course and no one explained to me the RHR so clearly as you did. Thank you!
Congrats, you just explained in 1.5 hrs what my physics teacher couldn't in 3 weeks. i might be able to pass my final now!, thank you.
did u pass
@@Antonio-nn8he i did pass! Got a B overall.
I really like how you take time and build up the difficulty of the problems. Really boosts up my confidence as well as my understanding unlike college lecture which assumes you understand everything and just throws out abstract equations without explaining them.
so true!!!
who’s watching this during quarantine
what's the logic of this comment?
@@kavyajain2210 lol
thank you so much for the work you put into these videos. the teachers at my school don't teach each topic specific enough, so i always have trouble in catching up. your videos help me a lot!! thankyou
thank you very much, sir, now it's been 6 years since this vid was made and yet there is no brief,excellent and understandable video of electromagnetism. you are so talented in a way you can make everyone to understand physics and the vids on chemistry and maths are also awesome . what a blessed mind , thank you.
I think you just saved my grade for an exam im cramming for. Thanks man!
You have no idea how much you have helped me! So informative and amazing! :)
Thanks man! you saved my life! great step by step explanation! Explaining every single detail, although the end part was a bit confusing I understood everything!
You have been helping me so much all summer. Just wanted to say how much I appreciate it man!
man you the best, at what you are doing am so grateful.
themba xulu Hi ,There are no coincidence in this life and I know for sure that GOD is giving all of us the chance to know him better and to make a relationship with him , and also have a great life : the answer is the prophet Muhammed Peace be upon him , he is the latest messenger from GOD to all mankind ,
Muslims were once the leaders of the world when they were practicing the commandement of the Curan ,
I know that you will delete this message but please take a few minutes of your time and make some research about it .
I am sending this message to everyone I can reach , everyone deserve to know the truth ,
Peace be with you and good luck.

What the fuck does this have to do with magnetism?
Lol
themba xulu I
Kobee R nice
you have a very calm voice that would attract even the deaf
Say what?
we found the deaf person lol
you are the brilliant JG im just wishing to see you atleast one day and im very thankful for your great videos and secondly, your explanation is 99 % clear
This is so helpful. I am only 16 min in and already have 3 pages of notes! Great details here! Bravo, Bravo!
got my physics exam in about 3 hrs, cramming in as much as possible.
How did it go?
How did it go
same.
How did it go?
I'm still curious to know your results.
Man, magnetism is easy af with your lessons! I couldn't understand a word when I read that on my book. Thanks )
I learn more from you than my actual teacher, you literally cover everything I learn in lesson, and I know once I get arch your video I’ll finish knowing that I now understand
7 years later an you are here helping me with physics ..ooh man you are awesome ❤
Dude. I've been to physics classes watched videos from M.I.T. professors and this video trumps all those guys. Keep it up. Thank you.
Thank you so much for this video!!
you are the man of Magnetism.....seriously outstanding
Thanks a lot! You did an amazing job, clearer than my teacher's lectures.
I am a huge fan of your videos! Everything from Organic Chemistry to Physics has been so helpful!
A friendly suggestion would be to add timestamps in your description to help your viewers follow along or skip to the part they are most confused about :)
just thank you, saved my life
Excellent excellent excellent!!! Thank you, information is still blessing those 5 years later, and will continue to do so going forward! 🙏
Thank you so much for this video! You basically explained all the concepts for magnetism in a relatively simple and short way. Loved the video :)
Man wtf i spend two week in class now learning a single thing and it only took one video to teach me everything????
This was really phenomenal. Thank you so much!!
New subscriber :)
I hope you have a good day as well! Just finished studying for my exam thats about 7 hrs from now. You're the best teacher, my tuition should be going to you
Your stuff is great, as is your manner of presentation. Thank you for the passion you have in getting the message across to even the 15 Watters like me!
Physics test tmrrow morning. Let's see how it goes hehe.
His notation of current out of page or into the page is incorrect.
Current flowing out of the page, meaning towards you the viewer, should be a dot.
Current flowing into the page, meaning away from you the viewer, should be an X.
I was just confused, figured it might help someone out.
I was wondering this too! I thought I had it backwards but glad to see someone else caught it.
you're my hero. cramming for an exam i haven't had a chance to study for because of work. is there somewhere we can donate to you? you got me through physics 1, you cover things in an hour that my prof takes 4 hours to do and you're so much more understandable. love your videos so much, thank you for all you do!!
love how you power through these
Wow what a great video thanks.
I thought I understood this pretty well, until I confused myself by looking through the bewildering array of right and left hand rules here on the internet. Your video regrounded my understanding, thank you. Those other rules, with variable assignment of fingers and hands depending on the circumstance, were just too confusing.
I have been watching your videos since my first year at the university, they helped me out thanks so much
Thanks man I finally understood magnetism ! I was struggling real hard for physics especially this chapter but you have saved me 😎
I should've skipped the last 2 weeks of class and just watched this video instead, sending links to everyone I know
Thank you very much. I'm Italian and I've found this video really helpful and useful because I've learned something about the magnetic field and part of the mathematical English language at the same time. Subscribed. 😃✅
No problem
Which software to you use to make your videos? :-)
Outstanding as usual, best teacher on the CZcams
Thank you so much! for compressing all of the chapter is such of an easy way to understand!
I came here without having a test to take urgently. I guess I'm improving.
Well, updates:
I left at once and I'm coming back now the test is tomorrow morning
@@o.g.dominus how did you do on the test?

That's why you the 🐐 man, easy to understand, clearly explained, practice understandable and logical. Just perfect and a big thankyou 🙏🏾
BLESS YOU SO MUCH. SECOND TIME WATCHING THIS VID IN MY LIFE AND ITS BLESSED ME EACH TIME
i understand everything even without a teacher teaching me anything about magnetism before the physics subject test. Props to you
shouldn't magnetic field (B) increase as distance from the wire (R) decreases?
yea i noticed that too
He meant increases, but he drew it as decreases
I noticed it too.
Yea he meant that
no because the strength looses as distance increase as density of field lines get decreased at a increasing distance
I am self studying my sat physics test and this helped a lot, thank you! You are a great teacher :)
Man you are just awesome brilliant explanation best physics lesson I ever had hands down
*Organic Chemistry Tutor* : posts
me, notices timestamp: *clicks 1.5/1.75 speed furiously*
me : also boosts the audio.
I just love this person ...can someone tell me his name ?? How he looks like ?? I want to see this genius
you are an excellent tutor and lecturer, keep the videos comming. I literally only study from your videos. thank you.
Thank you so much sir! Saved my semester! You are amazing
5:30 the arrow should point upwards for R, since it is reversible related to B.
at 5:55 the B suppose to increase when R decrease right...because its is inversely propotional.....??
Yea...that's what I thought??
He said the right thing but made the direction of the arrow wrong and yes you are right
Yeah, I was a bit confused
Yeah, I was a bit confused
Thank you so much man! You're videos are really helpful and am reviewing them before my exams. Really appreciate what you're doing!
you are the best youtube teacher i have found...... awesome teaching, great delivery and excellent information.
may God bless you abundantly..... big ups
May each and every one reading this comment be blessed and may Allah/God fulfill their heart desires.
Amin you too
Typo at 6:00 when R goes UP B goes down.
This is an excellent, really excellent explanation of Magnetic force and direction, I have had so much trouble with directions etc and this video really helped. Thank you
I would have failed if it weren't for u and ur free service. Dude deserves a noble peace price
