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
