Magnets: Properties and Uses

Magnets are objects made of special materials (like iron, nickel, cobalt, and steel) that can pull or attract other magnetic materials.
Some magnets are natural (like magnetite), while others are man-made from iron or steel and can be various shapes (e.g., U-shaped, horseshoe, bar).

Magnet Interactions

Magnets attract certain materials (magnetic materials).
Non-magnetic materials are not attracted to magnets (e.g., gold, silver, aluminium, wood, paper).
Magnets have two poles: north (N) and south (S).
Like poles (N-N or S-S) repel each other.
Unlike poles (N-S) attract each other.

Force and Magnets

A force is a push or pull.
Magnets exert forces on other magnetic materials.
Magnetic forces are strongest at the poles of the magnet.
Interactions between magnets result in forces of attraction or repulsion.

Types of Forces and Effects

Friction is a force that slows or stops moving objects.
Forces can change an object's motion (start, stop, or change speed/direction).
Forces can change an object's shape or size.

Magnet Uses

Magnets are used in many everyday devices: telephones, headphones, speakers, computers, video recorders, refrigerators.
Electromagnets are temporary magnets that become magnetic when electricity flows through them.
