The Ultimate Ring Jump Competition [FULL VERSION]

When a thick aluminum ring and a thin aluminum ring are opposed by a magnetic force and allowed to jump, the key factor that influences their behavior is the concept of electrical currents and resistance.
When a magnetic field changes near a conductor, it induces an electric current within the conductor. This current, in turn, generates a magnetic field that opposes the original magnetic field. According to Lenz's law, the induced magnetic field will always act to oppose the change in the magnetic field that caused it.
Now, when the rings are exposed to the magnetic field, the induced electric currents are generated in both rings. However, due to the differences in resistance and the skin effect, the behavior varies:
-- Thick aluminum ring: The lower resistance allows a larger current to flow through the thick ring. As a result, the induced magnetic field generated by this current is stronger. According to Lenz's law, this stronger magnetic field creates a greater opposing force to the applied magnetic force, causing the ring to jump higher until we put it in liquid nitrogen.
-- Thin aluminum ring: The higher resistance in the thin ring restricts the flow of current. Consequently, the induced magnetic field generated is relatively weaker. Therefore, the opposing force to the magnetic field is also weaker, resulting in a lower jump height compared to the thick ring. That is, until we add it to liquid nitrogen.

I wish all teachers where like this, these are so good I watch physics instead of random cat memes. Great video!

[@shmkrar1153]

Nice demonstration!

[@tamuphysastr]

Thank you!

[@BenRebuilt]

That was Awesome. I'm currently looking into this phenomenon on my own and I just wanted to ask, What do you guys think would happen if instead of an aluminum ring you used a ring shaped magnet? 👀

[@johnsk16]

Love these videos!

[@tamuphysastr]

And we love your reactions!

[@tobyhutchison]

Dawson! Whats up bro! Didn't know you were famous lol

[@othermoviestamil3680]

I love this channel
Your video so useful education

[@danielwong7119]

hey, do you guys have a name of the instrument you used in the video? I would love to try and build one for my students in high school so that they can learn the electromagnetism better. Thank you very much in advance.

[@jayalakshmi-kc9vq]

Amazing sir

[@user-vu1co3lz8v]

love channel my mum had her degree in science

[@williamthethespian]

Yay ! More phun with physics!!

[@TheRadioAteMyTV]

Why are so many college level experiments obsessed with liquid gasses? I just watched a lecture from London and she was using the stuff like candy too. It's not like we can all just grab that stuff and show our students if we aren't in college with giant budgets and safety abilities. Sigh.

[@tamuphysastr]

We do our best to have a good mix of both very low and high budget experiments on our channels. We do both because we teach high budget experiments in our classes, so we are knowledgeable experts on them. But we also like to show the simple stuff too, especially ones you can do at home, since this gives opportunities for anyone to play with science themselves.

[@TheRadioAteMyTV]

@@tamuphysastr That makes sense, it's just that liquid gasses exposure to other objects - that I have seen countless times - doesn't result in many variations, just turns stuff so brittle it crumbles, and that's about it, but it's so many college video or equivalents favourte toy to show how they can destroy countless objects. It's so wasteful at every level. Science needs to find a way to be far less wasteful.

is that titanium?

[@danielwong7119]

is it the Tesla coil?

[@RawrLess]

Neat
