Q.

Tape recorder should not be kept near one of the following things –

A. Clock
B. Magnet
C. Electrical switchboard
D. Radio
Answer» B. Magnet
Explanation: The cassette tape contains a magnetic strip wound around two spools. Tiny magnetic particles are randomly scattered throughout the tape. A tape recorder should not be kept near a magnet as the latter can cause the magnetic material to be pushed and pulled out of place. Rearranging the magnetic particles erases the sound.
