What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, primarily metals, and is produced by the motion of electric charges.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

What is an electromagnet?

Back

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

How do like charges interact?

Back

Like charges repel each other.

Front

How do opposite charges interact?

Back

Opposite charges attract each other.

Front

What is grounding?

Back

Grounding is the process of transferring excess electric charge to the Earth, which helps prevent static electric shocks.

Front

What factors affect the strength of an electromagnet?

Back

The strength of an electromagnet can be affected by the voltage of the power source, the number of wire turns around the core, and the type of core material used.

Front

What is a magnetic field?

Back

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

What is the role of a battery in an electric circuit?

Back

A battery provides the electrical energy needed to drive the flow of electric charge in a circuit.
