WHAT IS MAGNETISM?

•MAGNETISM REFERS TO PHYSICAL PHENOMENA ARISING FROM THE FORCE

BETWEEN MAGNETS, OBJECTS THAT PRODUCE FIELDS THAT ATTRACT OR REPEL

OTHER OBJECTS.

FORMS OF MAGNETISM:

FERROMAGNETISM• PERMANENT MAGNETS, MADE FROM MATERIALS

SUCH AS IRON, EXPERIENCE THE STRONGEST EFFECTS, KNOWN AS. THIS IS THE ONLY FORM OF MAGNETISM STRONG ENOUGH TO BE FELT BY PEOPLE.

MORE FORMS OF MAGNETISM:

DIAMAGNETISM

•MATERIALS ARE REPELLED BY A MAGNETIC FIELD.

FORMS OF MAGNETISM:

PARAMANETISM

•CERTAIN MATERIALS ARE ATTRACTED BY A MAGNETIC FIELD

FORMS OF MAGNETISM:

ANTIFERROMAGNETISM

•MAGNETIC PROPERTIES OF ATOMS OR MOLECULES ALIGN NEXT TO EACH OTHER

MAGNETIC FIELDS

•MAGNETS CREATE INVISIBLE AREA OF MAGNETISM ALL AROUND IT

•OPPOSITE POLES ATTRACT EACH OTHER

• ALIKE POLES REPEL EACH OTHER.

FUN FACTS!

• IF YOU CUT A BAR MAGNET IN HALF, YOU GET TWO BRAND NEW, SMALLER MAGNETS, EACH WITH ITS OWN NORTH AND SOUTH POLE.

• IF YOU RUN A MAGNET A FEW TIMES OVER AN UNMAGNETIZED PIECE OF A MAGNETIC MATERIAL (SUCH AS AN IRON NAIL), YOU CAN CONVERT IT INTO A MAGNET AS WELL. THIS IS CALLED MAGNETIZATION.
