Science Readiness: Electricity and Magnetism

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It usually consists of a coil of wire wrapped around a metal core, like a nail.

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

Back

A battery provides the electrical energy needed to power the circuit. It creates a flow of electric current.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, glass, and wood.

Front

What happens to similar charges in static electricity?

Back

Similar charges repel each other, meaning they push away from one another.

Front

What happens when an object gains electrons?

Back

When an object gains electrons, it becomes negatively charged.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is static electricity?

Back

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

Front

What is the difference between a magnet and an electromagnet?

Back

A magnet produces a magnetic field all the time, while an electromagnet only produces a magnetic field when an electric current is flowing.

Front

What are the two types of electric charges?

Back

The two types of electric charges are positive and negative.

Front

What is the function of wires in an electric circuit?

Back

Wires conduct electricity from one component of the circuit to another, allowing the flow of electric current.
