A magnet falls through a coil connected to a resistor. The induced current transfers energy to the resistor.
Compared with an identical fall through the same coil with its circuit broken, what happens?
The magnet experiences more magnetic resistance and reaches a higher speed.
The magnet experiences less magnetic resistance and reaches a lower speed.
The magnet experiences more magnetic resistance and reaches a lower speed.
The magnet experiences less magnetic resistance and reaches a higher speed.
