Electrical charges can move through them easily. Copper and aluminium are conducting materials.

Electrical charges can’t move througth them. Wood, rubber and plastic are insulating materials.

Electric current. Electric current is the movement of

electrical charges through a conducting material.› Parts of a electric circuit:

Current generator. Conducting elements or wires. Devices or receivers. Switch. Electricity meter. Protection devices or circuit breakers.

You can never separate the poles of a magnet. They repel each other if we put the same poles together. They attract each other if we put different poles together.

The magnetic poles of the Earth.

Our planet has a north magnetic pole and a south magnetic pole. They are very near its geographic poles.

Uses of magnetism.

Orientation. Magnets. Information storage. Theft control. Identification.
