Card 1Law of magnetism

State the law of magnetism.

Answer

Like poles repel and unlike poles attract. North pole and north pole repel. North pole and south pole attract.

Card 2Directive property of magnet

A magnet is suspended freely. In which direction does it come to rest?

Answer

A freely suspended magnet comes to rest in the north-south direction. The end pointing towards the north is called the north pole, and the end pointing towards the south is called the south pole.

Card 3Test for a magnet

Why is repulsion the sure test for a magnet?

Answer

Repulsion happens only when two magnets face each other with like poles. A magnet can also attract a plain iron rod, so attraction alone does not confirm a magnet. Repulsion proves that both objects a…

Card 4Magnetic poles

What is a magnetic pole?

Answer

The end of a magnet where the attractive property is maximum is called the magnetic pole. A magnet has two poles: north pole and south pole.

Card 5Magnetic poles in pairs

A bar magnet is broken into two pieces. What happens to the poles?

Answer

Each piece becomes a complete magnet with both poles. It is not possible to separate the two poles of a magnet. New poles are formed at the broken ends.

Card 6Magnetic field

What is the magnetic field of a magnet?

Answer

The space around a bar magnet in which the magnetic compass gets influenced is called its magnetic field. A compass needle changes direction at different points around the magnet because of this field…

Card 7Magnetic materials

Which materials are magnetic materials?

Answer

Iron, steel, cobalt, and nickel are magnetic materials. They are attracted by a magnet.

Card 8Non-magnetic materials

Which materials are non-magnetic materials?

Answer

Paper, wood, brass, plastic, copper, and aluminum are non-magnetic materials. They are not attracted by a magnet.
