Magnetism & Electric fields

What is magnetism?

• The force that attracts metals

• The ability of certain materials to attract or repel other materials

• The flow of electric current

• The movement of electrons

What is an electric field?

• A region where magnetic forces are felt.

• A force field created by moving charges.

• A vacuum where no forces exist.

• A region around a charged object where other charges experience a force
