Homework Statement
So I'm trying to prove to myself that energy is conserved in the case of magnetism. Here is the set up that I'm using to get that understanding (attached image).
Just to be clear the arrows represent the current lines and I am calculating a gain in PE because if I release Circuit 2 (after closing Circuit 1) I believe it will move in the direction of Circuit 1 (PE turns into KE).
Question: When I close the switch to Circuit 1 I create potential energy for Circuit 2. Where does the energy come from (I presume it comes from the current but don’t see how)?
Homework Equations
I suppose I could list the force equation
F = q v x B
This is really a baseline conceptual question; I already know how to calculate the force (I believe) and everything.
