When two objects pull toward each other
What is attract?
When matter has more positive than negative charges
What is a positive charge?
A magnet NOT made by people.
What is a natural magnet?
The point where the magnetic force is strongest.
What is a magnetic pole?
What will happen when a particle with a negative electric charge is placed near a particle with a positive electric charge?
A material that electrical charges cannot move through
What is an insulator?
When matter has more negative charges than positive charges.
What is a negative charge?
A magnet that cannot turn on or off

The push or pull of charged objects on each other.
What is an electric force?
When matter has no electric charge
What is a neutral charge?
What are the north pole and the south pole
the space where the force of a magnet acts; it is invisible
What is a magnetic field?
How are electric and magnetic forces similar?
The same charges/poles repel.
The opposite charges/poles attract.
