A student moves a magnet into two identical coils in separate trials. One coil is connected to an ammeter in a closed circuit. The other coil is connected only to a very high-resistance voltmeter.
The magnet follows the same path at the same speed in each trial. Which result is expected?
No current in the first circuit; a potential difference across the second coil.
A current in the first circuit; no potential difference across the second coil.
A current in the first circuit; a potential difference across the second coil.
No current in the first circuit; no potential difference across the second coil.
