MAGNETISM

______________-Refers to the properties and interactions of magnets in which there is a force of attraction or repulsion between like and unlike poles

____________________-Exerts a force on other magnets and objects made of magnetic materials (strongest ________ to magnet)

All magnets have a north pole and south pole

LIKE POLES ________ UNLIKE POLES ________

MAGNETIC MATERIALS

Only a few items such as ______, ________, and _________ are attracted to magnets or can be made into permanent magnets

__________________-Group of atoms with aligned magnetic poles (too small to be seen with eye)

__________________-Made by producing a magnetic material in a strong magnetic field, forcing magnetic domains to line up
