What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It consists of a wire wound into a coil, often wrapped around a ferromagnetic core.

What happens when you increase the number of coils in an electromagnet?

Back

Increasing the number of coils around the core increases the strength of the magnetic field, allowing it to pick up more objects.

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow freely. Examples include rubber, glass, and plastic.

What is a conductor?

Back

A conductor is a material that allows electric charges to flow freely. Examples include metals like copper and aluminum.

How do objects become positively charged?

Back

Objects become positively charged by losing electrons.

Front

How do objects become negatively charged?

Back

Objects become negatively charged by gaining electrons.

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 relationship between electric charge and electric force?

Back

Electric force is the attraction or repulsion between charged objects. Like charges repel, while opposite charges attract.

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

Back

A battery provides the electrical energy needed to move charges through a circuit.

Front

What happens to the electric field as an electron approaches a proton?

Back

As an electron approaches a proton, the attraction between them becomes stronger, resulting in a stronger electric field.
