AI Thread Summary
The aluminum foil rises in Faraday's and Lenz's Law demonstration due to the alignment of the induced current and magnetic field with that of the larger ring, resulting in attraction between their magnetic fields. The high resistance of the aluminum foil prevents it from being repelled by the coil when it is alone. This phenomenon illustrates the principles of electromagnetic induction and the interaction of magnetic fields. The discussion emphasizes the importance of understanding these interactions to explain the observed behavior. Overall, the rising effect is a clear demonstration of the principles of electromagnetism in action.

What is the actual explanation for the last demonstration, for why the ring rises up?o_O

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
 
The aluminum foil rises because the induced current and magnetic field are in the same direction as the larger ring. This means they are attracted because their magnetic fields align. However, the resistance is high enough that it is not repulsed by the coil when it is on there alone.

Ahhhh! I should have known.Thank you.
 

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
