Question

Which among the following will affect the magnet's strength?

• A. Heating
• B. Keeping in a dark room
• C. Keeping near electronic devices
• D. Painting

Answer 1

Answer: (A), (C)

The correct options are
A

Heating

C

Keeping near electronic devices

Painting doesn't have any effect on the magnetic strength, but the thickness of the painting should be small. When exposed to extreme temperatures, the alignment of particles will be destabilized; magnetic properties are then affected. Keeping a magnet near electronic devices can also affect its strength. This is because electronic devices have magnets inside them. Whenever a magnet is present in the vicinity of another magnet, both of the magnets are affected.
