Electricity and Magnetism: Non-Contact Forces

When two magnets repel each other which poles are facing each other?

• North and South

• South and North

• North and North

• Positive and Negative

What happens to the magnetic force as an object gets further away from the magnetic field?

• The force increases

• The force decreases

• The force stays the same

• There was no force to begin with

What is a conductor?

• A material that stops electric current from flowing

• A material that allows electric current to flow easily

Which is an example of a conductor?

• Glass

• Plastic

• Copper

• Wood

What is an insulator?

• A material that DOES NOT allow electric current to flow

• A material that DOES allow electric current to flow

Which is an example of an insulator?

• Rubber

• Copper

• Iron

• Steel

What is static electricity?

• The buildup of neutrons

• Electricity flowing through a current

• Particles staying still

• The buildup of electric charges on an object

What is current electricity?

• Current electricity involves a continuous flow of neutrons

• Current electricity involves a continuous flow of protons

• Current electricity is a single transfer of electrons

• Current electricity is a steady flow of electrons

What is magnetism?

• An invisible force produced by certain metals

• A visible force produced by certain metals

• An invisible force produced by all metals

• A visible force produced by mixtures of metals

How are the domains of a magnet organized?

• The domains are very weak

• The domains are all mixed up

• The domains all point in the same direction

• There are no domains
