What is electric current?
the flow of charged particles through a conducting wire
What is a permanent magnet?

Where on a magnet is the magnetic field the strongest?
at the poles
What is an electromagnet?
something that produces a magnetic field only when electric current passes through it

What is one thing that affects the strength of a magnetic field?
- how close you are to the magnet (closer = stronger)
- how large the magnet is (mass, size)
- what the magnet is made of (composition)
What is one way to make an electromagnet stronger?
- use a larger iron core (nail)
- use more wire turns
- use thicker wire
- use more or bigger batteries

What is the difference between an electrical conductor and an electrical insulator?
conductor = energy passes quickly
insulator = energy passes slowly
A magnetic material
