When you push a bar magnet towards a single-turn coil, you feel an opposing force. If the magnet is pushed towards a coil with many turns, why is the opposing force greater?
According to Lenz’s Law, the induced current in the coil opposes the motion of the magnet. When the coil has more turns, the induced emf and current increase, producing a stronger opposing magnetic field. This results in a greater opposing force felt on your hand.
