Ch. 1Sec. 2 Inside a

Magnet

atom• smallest particle of an

element that has properties of that element

central core of atom

positive charge

negative charge- creates magnetism

no electric charge

element• 1 of about 100 basic materials

that make up matter

magnetic domain• cluster of billions of atoms that all have

magnetic fields lined up in same way

• in magnetized material all or most of domains - arranged in same direction

ferromagnetic material

• material that shows strong magnetic effects

• common examples:

iron, nickel, cobalt

Making Magnets

• made from ferromagnetic material

• temporary magnet= easy to magnetize - loses magnetism quickly

• permanent magnet= keeps its magnetism

Making a temporary magnet

I predict that my temporary magnet (aka the nail) will pick up ________ paper clips.

ways to destroy

a magnet

dropit

strike ithard

heat it

• causes magnetic domains to become randomly arranged
