Magnet Race Car!

Observe how magnets interact at a distance when they are brought near each other.

Some forces can push and pull objects without touching. These forces can act at a distance and are called non-contact forces.

Place a magnet on a piece of paper and sprinkle iron filings over the magnet. What do you observe?

The pattern of the iron filings is the result of magnetic force. A magnetic force can act at a distance.

A magnet is an object with a magnetic force. A magnet can pull or attract objects made of certain metals such as iron and nickel. A magnet cannot attract objects made of plastic, wood, rubber or glass.

A magnet has two poles – a North pole and a South pole. When the like poles of two magnets are brought together, they push or repel each other. When unlike poles are brought together, they pull or attract each other.

Many objects make use of magnets. Some doors used magnets to keep them closed. A maglev (magnetic levitation) train has magnets that repel it from the track. This reduces friction and allows the train to travel at fast speeds.

Magnets are also used for medical imaging and storing data on computer disks.
