Hello everyone.
I'm trying to understand how an 'induced' emf behaves on a current carrying conductor.
Basically the example that's giving me problems is in the case of a motor, if a current starts to pass through a coil it will get an induced 'emf' to oppose the motion. And hence it seems the current drops as the motor reaches a stable speed.
My question lies in 'how' it acts, I'm imaging a current in one direction, being passed another current of opposite direction, but why doesn't it 'get stronger/reaches a emf to completely oppose the motion'?
Thank you
