The Danish professor Hans Christian Oersted was the first
person to discover electromagnetic force, which could be
created by an electric current. Although Andre-Marie Ampere
was the first one to explain the relationship between electricity
and magnetism, Oersted is the reason we have motors and
actuators today (Sharkawi, 2012).
As an electrical instrumentation specialist for a wastewater
industry, I find Oersted’s discovery significant to electrical
power. As stated above this is the basis for the motor,
actuators, and many other instruments I encounter every day.
There are so many ways that Oersted’s discovery of electricity
and magnets are used such as electrodynamics and
electromagnetic induction, and has led to the creation of
transformers, light, radio waves and the electromagnetic
spectrum, particle accelerators, maglevs, and electromagnets.
Other applications of electricity and magnets are speakers,
where a magnet pulls a cone back and forth to create sound
waves. Televisions use magnets to control electrons that are
being forced across the screen. The medical machine known as
the “CAT scan” can detect electrical activity in a human and
uses magnets to make an image out of it. The final example is
one that helps us understand ourselves better. This is the
human brain, and although it was not invented or discovered by
Oersted, we now can better understand it. The human brain in
constantly creating electrical impulses to create actions within
our bodies (Rod, 2017).
