Electricity and Magnetism Review

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily.

Front

What happens to the magnetic field strength when electrical current increases in an electromagnet?

Back

When current is increased, magnetic field strength increases.

Front

What are the two ends of a bar magnet called?

Back

The two ends of a bar magnet are its magnetic poles.

Front

What happens when two objects with negative charges come into close contact?

Back

They will repel.

Front

What is an electromagnet?

Back

An electromagnet is a device that generates a magnetic field when an electric current passes through it.

Front

What is the relationship between voltage and current in a circuit?

Back

Voltage is the force that pushes electric charges through a circuit, and current is the flow of electric charges.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects.

Front

What is the role of an insulator?

Back

An insulator is a material that does not allow electrons to flow easily.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

What is magnetic field strength?

Back

Magnetic field strength is a measure of the intensity of a magnetic field, often represented by the symbol 'B'.
