Introduction
Electromagnetic field is
nothing more than the combinations of magnetic and electric field. This field
exerts a force on particles that possess the property of electric charge, and
is in turn affected by the presence and motion of those particles. Before
diving into “Electromagnetism”, we have to know how to distinguish the
differences between electric and magnetic field. After knowing the property of
magnetic field and magnetic force, we can investigate the different types of
magnetism: ferromagnetism, paramagnetism, and diamagnetism. We can then use
these different types of magnetism to apply it to our daily life.
