Exploring the Forces of Magnetism

Front

What is electromagnetism?

Back

Electromagnetism is the branch of physics that deals with the interaction between electric charges and magnetic fields.

Front

What is an application of electromagnetism?

Back

Electric motors are a key application of electromagnetism, converting electrical energy into mechanical energy.

Front

How does a magnetic force act on a current-carrying conductor?

Back

A magnetic force creates a force that is perpendicular to both the direction of the current and the magnetic field.

Front

What is electromagnetic induction?

Back

Electromagnetic induction is the process by which a changing magnetic field can induce an electric current in a conductor.

Front

What is the principle behind electromagnetic induction?

Back

A magnetic field can induce an electric current in a wire.

Front

What happens in a coil of wire during electromagnetic induction?

Back

An induced electric current is generated in the coil of wire.

Front

What are magnetic domains?

Back

Magnetic domains are regions within a magnetic material where the magnetic fields of atoms are aligned.

Front

What is a magnetic field?

Back

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

Front

What is the right-hand rule in electromagnetism?

Back

The right-hand rule is a mnemonic for understanding the direction of the magnetic force, current, and magnetic field.

Front

What is the difference between permanent magnets and electromagnets?

Back

Permanent magnets maintain a constant magnetic field, while electromagnets generate a magnetic field when an electric current flows through them.
