Electricity and Magnetism

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

• Opposite Poles
• 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
• a material with tightly bound electrons

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
• A material with loosely bound electrons

Which is an example of an insulator?

• Rubber
• Copper
• Water
• Steel

What is static electricity?

• The buildup of neutrons
• Electricity flowing through a current
• Particles staying perfectly 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

How do you increase the strength of an electromagnet?

• Decrease the number of batteries and increase the number of coils
• Increase the electric current and decrease the batteries
• You cannot strengthen an electromagnet
• Increase the electric current and increase the number of coils
