I got the same practical tomorrow
Realllllly helpful
Thanks

your pens are pretty

[@vishalsathiaseelan679]

Great video sir. Thank you very much. Really needed it for practical lab.

[@jcicrafters]

Amazing! Tysmmmm!!!!

Why does the wire moving up cause the yoke to move down? Coz after all the wire is not touching the yoke to exert the force.

[@ScienceShorts]

The wire doesn't need to touch the magnets to feel a force - exaclty the same for the magnets!

Hi which exam boards are most likely to bring up the DC rippling?

[@ScienceShorts]

AQA have an unhealthy obsession with it.

4:25 how does this work? I have in my head because of newtons equal and opposite reactions...but can someone give another example/analogy? Please

[@michealmclaughlin991]

Great video btw

[@ScienceShorts]

If you push on a wall that doesn't move, the wall exerts an equal and opposite force on you, and you move. You're the magnet on the balance in that example.

Isnt percentage uncertainty=(LOB fit- LOW fit)/LOB fit x100? thanks

[@user-vh3zm7yf5j]

I think he is referring to the maximum gradient (which is still an example of a line of worst fit). What you're referring to is when you use max and min gradient then it would be LoBF - min gradient / LoBF x100
Hope this makes sense

[@Terrorblazer]

can you alter magnetic flux density by changing how close the magnet is to the wire

[@ScienceShorts]

If the poles are closer together, the field will be stronger, yes.

[@hardeepsaini1171]

How are we changing the current? Is it through the use of the variable resistor? But you can't change current through a resistor, right?

[@EvoVFX]

bit late but changing resistance does change current

[@hardeepsaini1171]

@@EvoVFX so does that mean the potential is constant?

final A2 exam 😻

I just thought you should know that you forgot to edit in the card of where you do the practical by yourself at the end.
