Question

Yogesh takes a magnetic compass in the lab and tries to show how it works to his friends. But,

it does not work well in the laboratory. It just swings to and forth. He then takes it out in the

field and it started working. What do you think could be the possible reasons for this?​

Answer 1

Reasons for the magnet to stop working:

• The needle in the magnetic compass is a small magnet. It points the north and south pole with the help of earth magnet.
• When the magnetic compass is near or in the strong magnetic field, it starts to swing.
• When it is taken out of that field, then the magnetic needle works as usual.
• For example, when a magnetic compass is placed near the refrigerator, the compass does not point correctly.

Answer 2

Explanation:

•The lab was full of Electronic Appliances.

• That may have high magnetic effects.

•The magnet in the compass needle is small that can not work in strong magnetic field ( i.e. field in the room.

•If it is back in normal environment, then it will back its magnetism also.
