Magnetism and Induction

Front

What generates magnetism?

Back

Magnetism is generated by moving electrons.

Front

What device converts magnetism into electricity?

Back

Electric generator.

Front

What happens to the magnetic force as the distance between two magnets decreases?

Back

The magnetic force increases.

Front

What device converts electricity into magnetism?

Back

Electromagnet.

Front

What happens when two like poles of magnets are brought close together?

Back

They will repel each other.

Front

What is the definition of magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the role of an electric motor?

Back

An electric motor converts electrical energy into mechanical energy.

Front

What is the difference between permanent magnets and electromagnets?

Back

Permanent magnets produce a constant magnetic field, while electromagnets can be turned on and off and their strength can be adjusted.

Front

What is magnetic induction?

Back

Magnetic induction is the process by which a material becomes magnetized in the presence of a magnetic field.
