How is an electromagnet different from a permanent magnet?

  • A) Permanent magnets can be turned off; electromagnets cannot.
  • B) Electromagnets can be turned on and off; permanent magnets are always magnetic.
  • C) Permanent magnets need electricity to work; electromagnets do not.
  • D) Only permanent magnets have a magnetic field.

 B Explanation: An electromagnet only works when electricity flows, meaning it can be turned on and off

An electromagnet only creates a magnetic field when electric current is flowing through its circuit.

  • True
  • False

True Explanation: This demonstrates the relationship between electricity and magnetism—the magnetic field is only active when the current is turned on

How can you turn a steel paperclip (a magnetic object) into a temporary magnet?

  • A) Rub it in one direction with a strong permanent magnet.
  • B) Wrap it tightly in plastic or rubber.
  • C) Connect it to a battery without using any wires.
  • D) Heat it up to release static charges.

A Explanation: Rubbing a steel object with a permanent magnet turns it into a temporary magnet

 A student builds an electromagnet using a battery, wire, switch, and iron nail. Closing the switch (allowing current to flow) attracts paperclips. Opening the switch drops them. What does this prove?

  • A) Electricity and magnetism are completely separate systems.
  • B) An electric current flowing through a circuit creates a magnetic field.
  • C) Opening the switch makes the electrical current flow faster.
  • D) The iron nail has permanently changed into a permanent magnet.

 B Explanation: This demonstrates the relationship between electricity and magnetism—the flowing current creates a magnetic force
