I'm new to the wonderful world of physics, and I'm really confused about magnetism and induced currents.
Let's say we have 2 circular closed loops that each carry a current $I$ clockwise and the loops are placed on top of one another. Now if the current in the top loop was to decrease to $0$, by Lenz's Law, what happens to the current in the bottom loop?
I said that if the current was to decrease to $0$ in the top loop, then an induced magnetic field will be created that's coming in the plane as opposed to out the plane (looking at the loops from the top). It will be in the same direction as the original magnetic field created from the first loop. So because the original magnetic field is nonexistent, then the only current in the bottom loop would be the induced one (which is clockwise by R.H. rule), so the current would decrease.
Again, I really don't know how to approach this question it's really confusing for me. Any help is greatly appreciated.
