Electricity and Magnetism Quiz

Why are electricity and magnetism considered intertwined?

• They are both caused by the interaction of positive and negative charges in matter.

• They are both only caused by negative charges.

• They are unrelated forces in physics.

• They are both only caused by positive charges.

What happens when the number of protons and electrons in an atom are the same?

• The atom becomes positively charged.

• The atom becomes negatively charged.

• The positive and negative charges cancel each other out and the atom is neutral.

• The atom does not exist.

What term is used to describe a positively or negatively charged atom?

• Electron

• Proton

• Neutron

• Ion

What happens when an atom gains electrons?

• It becomes positively charged.

• It becomes negatively charged.

• It becomes neutral.

• It becomes an ion.

What is the term for the area around an electric charge that experiences the force exerted by the charge?

• Magnetic field

• Gravitational field

• Electric field

• Force field

What is the relationship between the strength of an electric field and the distance from the charge?

• The field gets stronger as you get closer to the charge.

• The field gets weaker as you get closer to the charge.

• The field strength is constant regardless of the distance from the charge.

• The field strength is not related to the distance from the charge.

What is created when an electric charge builds up on an object and transfers from one body to another?

• Electric current

• Electric discharge

• Static electricity

• Magnetic field

What is the effect called when a charged object placed near another object causes the nearby objects to become charged as well?
