Magnetism A force of attraction and repulsion

Poles of a Magnet Law of Magnetic Poles North and South Area where the magnetic force is the strongest North and South (N & S) Law of Magnetic Poles Opposites attract & Likes repel Poles CANNOT be separated!!!

Magnetic Field A region around a magnet where the force is the strongest N S The strength of the field decreases as the distance from the field increases.

Magnetic Domains NOT A MAGNET!!! When all of the domains are lined up, the object becomes magnetized

Demagnetizing a Magnet A magnet is no longer a magnet The domains are not lined up anymore Ways to Demagnetize a Magnet 1) Heating 2) Dropping 3) Other Strong Impact
