What is the nature of Nickel in terms of magnetism?

Back

Nickel is a magnetic material.

Front

Why is a compass needle attracted to the North?

Because it is being attracted to the Magnetic South Pole.

Front

What surrounds every magnet?

Back

A magnetic field.

Front

What does electric current passing through a wire produce?

Back

A magnetic field around the wire.

Front

How does the force of magnetism change with distance between magnets?

Back

The force of magnetism is stronger when magnets are closer together.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

What is the difference between a permanent magnet and an electromagnet?

Back

A permanent magnet maintains its magnetism without external power, while an electromagnet requires electric current to generate a magnetic field.

Front

What materials are typically used to make permanent magnets?

Back

Materials like iron, nickel, cobalt, and certain alloys.

Front

What happens to the magnetic field when the current in a wire is increased?

Back

The strength of the magnetic field around the wire increases.

Front

What is the right-hand rule in magnetism?

Back

A method to determine the direction of the magnetic field around a current-carrying wire.
