Magnetism Formative

Front

What is magnetism?

Back

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

Front

What are the two poles of a magnet?

Back

Every magnet has a north pole and a south pole. Opposite poles attract each other, while like poles repel.

Front

How does the size of a magnet affect its magnetic force?

Back

Larger magnets have stronger force.

Front

What materials are attracted to magnets?

Back

Iron, cobalt, and nickel are the three metals that attract magnets.

Front

What is a magnetic field?

Back

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

Front

What happens to a compass needle in a magnetic field?

Back

A compass needle aligns itself with the magnetic field, pointing towards the magnetic north.

Front

What are magnetic field lines?

Back

Magnetic field lines are invisible lines that represent the strength and direction of a magnetic field. They form closed loops and never cross.

Front

What is the right-hand rule in magnetism?

Back

The right-hand rule is a method used to determine the direction of the magnetic force, magnetic field, or current in a conductor.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in a magnetic field.

Front

What is electromagnetic induction?

Back

Electromagnetic induction is the process of generating electric current from a changing magnetic field.
