Question 18

A vibration monitor contains a thin conducting strip attached to a spring and connected to a sensitive voltmeter. For each test, a permanent magnet is either placed beside the strip or removed from the monitor.

Which of the following situations would cause a potential difference to be induced across the strip?

[1]
A

The strip remains stationary beside the stationary permanent magnet.

B

The strip and permanent magnet move together, keeping the same separation.

C

The strip vibrates after the permanent magnet is removed from the monitor.

D

The strip vibrates while the permanent magnet remains stationary beside it.
