Hi ya guys,

 

Here is my question:

 

In a coil with some DC current, one can think of all of the electrons moving inside as a cylinderical electron cloud, spining around the cylinder's axis.

 

Is it equivalent to think of the self induction of a coil as the angular momentum of this electron cloud?

 

The coil's resistance to the current's change is analogous to the resistance of an object's angular momentum to change.

 

What do u think?

that's what i was thinking. maybe if you make the coil smaller it will make it go faster?

I didn't think about it, but it sounds like you're right.
