Magnet Magic - Lenz's Law 

High quality exercise bicycles use Lenz's Law to add resistance--rather than friction, which wears out the parts.

Let's make a one-way copper elevator shaft and give everyone magnetic vests.

I was unaware of Lenses Law. Thank you for the demonstration and explanation. What I would have liked to see was you connecting an electrical measurement to the copper tube to determine the level of electrical impulse created following Lenses Law.

Thank you sir, great video and explanation

Thanks for the awesome video! Appreciate the effort.

Imagine if we could create some kind of metallic structure of copper, that reverses the induced magnetic field, so that instead of opposing the direction of the magnet, it adds to it. I know it couldn't be done, but an interesting thought none the less.

Great presentation of a difficult to explain interaction :-)

மிக அருமை... மிக்க நன்றி....

amazing video. Thank you

It's a really fantastic explanation sir

it attained a terminal velocity

In U.S. military magnetic compasses such as those manufactured by the Cammenga Company, the magnetic card is dampened using this principle. Many compasses use liquid dampening of the needle. The U.S. military did not want a liquid filled compass. The U.S. lensatic compass has a copper ring around the circumference of the compass housing. The magnetic needle induces a magnetic field in the copper ring and this serves to brake or dampen the compass needle. Induction dampening.

Thank you ....

Nice job Keep the videos coming .... joined

Amazing

So does the magnet slows down only in a copper pipe or in any non-attracted pipe to the magnets?

I'm doing this for my science fair. Can you generate electricity and use it to light a led light from the copper tube while the magnet falls down? Pls answer and I never had physics class so pls don't hate

where from u are

Wow

on peut utilise cette mecanisme un systéme de frenage

A slight correction in your short definition of Lenz's Law: An induced magnetic field does not really oppose the field that induced it. What it actually opposes is the CHANGE in the original magnetic field. So if the original magnetic field is diminishing the induced magnetic field will supplement rather than oppose it, trying to stop it from diminishing.
