kek, I didn't believe in Ohm's Law as a kid because I didn't know about non-ideal circuit elements like real batteries with non-zero ESR
anyway, brains grow through exercise, which is just what you're doing. Pic related shows the general case which will help you frequently in circuit analysis. there's a dual law wrt current which is also helpful in understanding parallel loads and such, you can look it up

that's a tough one. you're not likely to get away without some custom magnetics
maybe you could rummage around some of the online surplus stores like All Electronics to see if they have a coil already wound or assembly already made that you could adapt to your purpose with some sort of control elements
