Lecture 29– Faradays Law and Lenz Rule

Levitation of a cubic magnet

Jumping Ring

Falling magnet in a metal tube

Demo:

side view:

Lenz Law: Current loop has magnetic inertia.

It has the tendency to maintain its flux state.

Initial: 10 lines out

Next: 12 lines out (2 lines in to maintain original 10 lines out status

Application: Falling magnet in a metal tube

Demo: The falling magnet moves slowly

Do the current below the magnet

You will do the case where the loop is above the magnet.

The loop has magnetic inertia:

Now: 3 lines 

Next: 5 lines 

Now for the current loop above the magnet

Now: 3 lines 

Next: 1 lines

It affects the falling magnet:

Jumping Ring Demo:

Show current loop as magnetic initial.

After we turn on B of the solenoid, the ring jumps away to maintain net flux state.

Understanding the force affecting the ring:

= stronger lifting force
