Magnetism and Electromagnetism Unit 1 – Magnetism
UNIT 1 – MAGNETISM
UNIT OBJECTIVE
At the completion of this unit, you will be able to describe and demonstrate the effects of
magnetism by using magnets and a compass.
UNIT FUNDAMENTALS
Magnetism is a phenomenon that occurs naturally in some metallic materials. It can also be
produced by electrical currents (electromagnetism). In this unit, you will learn about natural
magnets.
Magnets exert a force on other magnets. This force may cause the magnets to attract each other
(attractive force) or to repel each other (repulsive force).
Magnets also exert a force on other magnetic materials that are not magnets themselves. These
materials will be discussed later.
