Question

1. Write a short note on 'Care of Magnets'.
2. What are magnets used for?​

Answer 1

Answer:

1.

Care should be taken not to drop them or allow them to be exposed to heat (high heat, like someone holding them over a flame) because this will cause the tiny magnetized bits inside to lose allignment and cause the magnet to lose strength. Most magnets today are ceramic or very powerful rare earth metal.

2.

Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.
