Making & Destroying Magnetism
MAKING A MAGNET
The two methods of making a magnet are:
1.Electrical Method (using a direct current)
When viewed from the ends:
If the current flows in a clockwise direction, you are looking at the south (blue) pole. If the current flows in an anticlockwise direction, you are looking at the north (red) pole.
2. Stroking Method
DESTROYING MAGNETISM
The methods for destroying magnetism are:
1.Hammering
2.Heating
3.Alternating current method
(Also By Induction)
The law of magnetism states that like poles repel each other and unlike poles attract each other.
