Smallest particle of an element – ATOM Proton- inside nucleus and carries

positive charge Neutron- inside nucleus and carries no

charge Electron- surrounding nucleus and carried

a negative charge A spinning electron produces a magnetic field

that makes the electron behave like a tiny magnet

Magnetic Domain- a group of atoms that have their magnetic fields aligned

In a magnetized material, all or most of the magnetic domains are arranged in the same direction

Ferromagnetic Material- a material that shows strong magnetic properties Ex: iron, nickel, cobalt, gadolinium

Ferrite – mixture of substances that contain ferromagnetic materials Ferrite is most commonly used magnet, but

are brittle and chip easily

Magnets can be made, destroyed, or broken apart

Temporary magnet- a magnet made from material that easily loses its magnetism Ex: needle, paperclip

Permanent Magnet – a magnet made from a material that keeps its magnetism for a long time

If you break a magnet in two… you get two new magnets!
