MAGNETISM Fact Sheet
Below are some basic facts about magnets and how they behave:
 A magnet is a material containing ________, and is called a
__________________ material.
 The 4 primary ferromagnetic materials are denoted by INCS: _________,
___________, ___________ and ____________.
 The “king” of all ferromagnetics is _________.
 A magnet has two ends called _________, one of which is called a north pole
or north-seeking pole, while the other is called a south pole or south-seeking
pole.

ANSWER KEY
Below are some basic facts about magnets and how they behave:
 A magnet is a material containing iron, and is called a ferromagnetic
material.
 The 4 primary ferromagnetic materials are denoted by INCS: iron, nickel,
cobalt and steel.
 The “king” of all ferromagnetics is iron.
 A magnet has two ends called poles, one of which is called a north pole or
north-seeking pole, while the other is called a south pole or south-seeking
pole.
 The north pole of one magnet attracts the south pole of a second magnet,
while the north pole of one magnet repels the other magnet's north pole. So
we have the common saying: like poles repel, and unlike poles attract.
 A magnet creates an invisible area of magnetism all around it called a
magnetic field, consisting of lines of flux.
 The lines of flux are directional; they exit the north pole of a magnet and
enter the south pole.
 As with the Earth, gravity is based on mass, while magnetism is based on the
material that the object is made of.
 If you cut a bar magnet in half you get two brand new, smaller magnets, each
with its own north and south pole.
 In an unmagnetized material, the magnetic domains are pointing in random
directions, while in a magnetized material, the domains are parallel to each
other.
 Electromagnetism is the effect by which electric currents produce magnetic
fields. When an electric current flows, a magnetic field is created and
whenever a magnet moves, an electric current is produced.
 Magnetism operates on the atomic level, with the negatively charged
electrons and positively charged protons.
