Electricity (2018)

ALL magnets have a (n) ____________________________

• North pole
• South pole
• East and west pole 
• North and south pole

The area surrounding magnets where there is an attraction or a repulsion is called the:

• electrical field
• magnetic charge
• magnetic field
• electrical charge

Temporary magnets are called____________________

• Bar magnets because bar magnets can be turned on and off.
• Bar magnets because they cannot be turned on and off and cannot be demagnetized.
• Electromagnets because they cannot be demagnetized.
• Electromagnets because they are powered by electricity and can be demagnetized.

What happens when you disconnect electromagnets from an energy source?

• They break apart, causing the poles to stop attracting each other.
• They demagnetize because the electrical current creating the magnetism has lost its energy source.
• They demagnetize because the poles have switched positions.
• They demagnetize because both poles become positive when the energy source is disconnected.

______________ electricity is a build up of electrons.

• Static electricity because this type of electricity is not moving electricity.
• Current electricity because this type of electricity is moving electricity.
• Current electricity because the charges are unbalanced.
• Static electricity because the electrons are moving through a conductor.
