Electricity, Magnetism, and Electromagnet Practice

Front

What happens when you walk across a carpet and pick up electric charges?

Back

You can become electrically charged, and when you touch a conductive object like a doorknob, the excess electrons can discharge, causing a shock.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it freely.

Front

What are magnetic domains?

Back

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

Front

What must happen for a metal to become a magnet?

Back

The magnetic domains in the metal must be aligned.

Front

What occurs when two objects have opposite charges?

Back

They attract each other.

Front

What occurs when two objects have the same charge?

Back

They repel each other.

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 electrons in electric charge?

Back

Electrons carry a negative charge and are responsible for electricity.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it freely.

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) changes direction periodically, while DC (Direct Current) flows in one direction.
