Lesson 10, Topic 6
This is a process in which a magnet is made to lose its magnetism. This can be achieved by
- Electrical method
- Mechanical method
- Heating method
- Electrical Method – The magnet is placed in a solenoid and alternating current (a.c) passed through it. When the magnet is withdrawn from the solenoid in the east-west direction, the magnet will lose its magnetism
- Mechanical method – Hitting or dropping the magnet on the floor several times while pointing it in the east-west direction, the magnet will lose its magnetism
- Heating method -Heating the magnet red hot and allowed to cool in the east-west direction makes the magnet lose its magnetism.
