Exploring Magnets

Answer

Magnetic materials are materials that are attracted towards a magnet. Examples include iron, nickel, cobalt, and some of their combinations with other metals. Steel (which contains iron) is also magne

Answer

Non-magnetic materials are materials that are not attracted towards a magnet. Examples include wood, plastic, rubber, glass, paper, copper, aluminum, and gold.

Answer

The two poles of a magnet are called the North pole (N) and the South pole (S). The North pole points towards the north direction when the magnet is freely suspended.

Answer

No, we cannot obtain a magnet with only one pole. Even if we break a magnet into smaller pieces, each piece will always have both North and South poles. A single North pole or South pole cannot exist

Answer

Iron filings stick most near the two ends (poles) of the bar magnet. Very few iron filings stick to the middle part of the magnet. This shows that the magnetic strength is maximum at the poles.

Answer

When a bar magnet is freely suspended, it always comes to rest in the north-south direction. The end pointing north is called the North pole, and the end pointing south is called the South pole.

Answer

A freely suspended magnet points in the north-south direction because the Earth itself behaves like a giant magnet. The magnet aligns itself with Earth's magnetic field.

Answer

A magnetic compass is a device used to find directions. It has a magnetized needle that can rotate freely. The needle aligns itself with Earth's magnetic field and points in the north-south direction.
