Abstract

Electromagnetism is any field that studies the
interaction of particles that are electrically charged.  Domains cluster around iron molecules in tiny
magnetic fields; because they are not arranged in an organized way, iron is not
magnetic on its own, but can be acted on by other magnets. Domains in ferrous
metals can be temporarily activated by a flowing electric current. Electric and
magnetic forces do not behave alike; electric forces come from electric charges
whereas magnetic forces come from moving charges currently in motion.

Electromagnetism is used in many current items such as hard disk drives, motors,
generators, speakers, and magnetic resonance imaging machines. New research in
electromagnetism has shown a “camelback effect” where two lines of equal poles
are charged oppositely and separated by distance, which showcases a new class
of magnetic trap that can be used with cylindrical magnets. Thanks to research
done on electromagnetism, there is a possible new future where antennas can be
found on computer chips, which are currently a limiting factor in smaller
designs since below a certain sizes, losses are too great. Meanwhile, in daily
life, electromagnetism makes Maglev trains, induction cooking, microwaves, and
even wall clocks possible. Electromagnetism is a challenging topic with much to
still be learned.

 

 

Electromagnetism and Ferrous Material

Any metal that contains iron is known
to be ferrous. These common metals create domains to attract magnetic fields,
and are the only things attracted by a magnetic field. Domains cluster around
iron molecules in tiny magnetic fields, each with its own polar line that can
face in different directions from the other molecules. Because these domains
are not arranged in any kind of organized way, iron is not magnetic on its own,
but can be acted on by other magnets. Domains in ferrous metals can be
temporarily activated by a flowing electric current (Priddy, 2017).

Electromagnetism

Electromagnetism is magnetism that is
developed by an electric current. Until the 1800s, electricity and magnetism
were not recognized together, but as separate forces. Electric and magnetic
forces do not behave alike; electric forces come from electric charges, whereas
magnetic forces come from moving charges that are currently in motion (Kashy,
McGrayne, and Robinson, 2016). The study of electromagnetic fields, sometimes called
electromagnetic induction, observes when an object becomes charged
electrically. In a certain range of frequency, some electromagnetic fields are:
radio waves, infrared waves,  ultraviolet
waves, and x-rays. Electromagnetism can only be observed when there is an
electrical current running.

Importance of Electromagnetism

Electromagnetism has been a strong and
influential force in modern society. Electromagnetism is used in many current
items including and not limited to hard disk drives, motors, generators, speakers
and magnetic resonance imaging machines (Kashy, McGrayne, and Robinson, 2016).  Electromagnetism is a major utility in most
jobs, and is heavily depended on. Without electromagnetism it would become
increasingly difficult for scrap yards to lift heavy pieces of metal, Maglev
trains that use magnetic repelling to levitate wouldn’t be able to work and
alternate travel would become severely slower, induction cooking wouldn’t
exist, all of which people depend on for their own convenience and their
safety.

Research
on Electromagnetism

Recently International Business Machines
Corporation (IBM) has released information about a new discovery in
electromagnetism.  The IBM team has
deemed this new effect the “camelback effect.” shows two lines of equal poles
charged oppositely and separated by distance. A dipole’s length must exceed a
certain size before the field becomes more intense near the edges and produces
a field that resembles the humped back of a camel. This discovery showcases a
new class of magnetic trap that can be used with cylindrical magnets whose
poles affect a graphite rod as a trapped object (IBM Blog Research, 2017).

Results of Experiments with
Electromagnetism

            Thanks to the research done on
electro-magnetism there is a very possible near future with antennas on computer
chips. These chips could provide an extraordinary piece to connecting
electro-magnetism and quantum physics. These are the important future
considerations in semiconductor research. A research team from Cambridge
University made the groundbreaking discovery that antennas are one of the
limiting factors when trying to make smaller designs, since below a certain
size, the losses are too much (University of Cambridge, 2015). This will change
the limits of modern technology and lead to unbelievable advancements of
today’s world.

Benefits of
Electromagnetism

Electromagnetism is
responsible for a lot of things we take for granted, because electromagnetism allows
for the switching on and off of electricity as required. No matter the device,
from wall clocks to microwaves, all have electromagnetics used in their
function. Plenty of appliances in the home rely on electromagniestism.  An electric fan works using electromagnetic
induction principle, which keeps blades rotating, making the blade hub the fan
rotation, which blows air (Balu, 2011). Electromagnetism
has had outstanding affects toward the modern-day world and very few if any
negative ones. The research of this topic has had many health benefits to both
humans and animals, the main one being that it led to the creation of the
magnetic resonance imaging machine, which uses electromagnetism to do
essentially a non-radiation X-ray. It’s also led to faster travel.

Conclusion

The field of electromagnetism has had a
vast impact on modern life. Without it, even the most common daily activities,
from checking the time to traveling to work, to making dinner or even turning
on a light switch, would not be possible. In the future, electromagnetism could
yield even greater changes for society as computer chips with antennas enable
even smaller technology to integrate into daily life, may
even lead to travel in space using ion propulsions systems that generate
magnetic fields in order to accelerate ions for thrust (Williams, 2016). One
thing is clear about this complex and fascinating topic:
Electromagnetism’s potential for changing the way we live is far from finished.
