Electromagnetism Essay, Research Paper
Electromagnetism exists everywhere. When people drive, walk, or even go to the
beach. However, due to the extreme complexity of the topic, electromagnetism has
proven to be a subject studied by those who are crafty and willing enough to
explore the domain. The ideas of electricity start from simple objects such as
springs, coils and magnets that simply created a current for some sort of affect
to either start or light some object. Now these theories have expanded to a
point where our everyday lives are affected by it. When people start their cars
for example, a magnet turned by a flywheel generates current through coils to
help ignite the cars electrical system. In short, electromagnetism exists
everywhere in our everyday lives. There are many examples of electromagnetism
effecting technical objects of today?s society. One particular example would
be radar devices used for tracking ships, cars, or even submarines. The ideas of
sending out a signal composed of a wave of certain frequency and wavelength
returned at a certain time can be used to find objects or map out underwater
territory. Use of similar techniques allows for policemen to radar speeds of
drive-by cars. Although, crafty engineers have created stealth devices that are
able to mask their speed by accepting the radar beam and by scrambling it via
frequency changes or simply send the same signal back at a delayed time thus
justifying a slower speed. This is just a mere fraction of the uses of
electromagnetism. Another possible use for electromagnetism would be on the vile
side of destruction. There are many aspects of electromagnetism. One of the
fiercest uses is as a weapon. EM guns, tanks, and devices are harmful and more
dangerous than normal guns and missiles due to their non-ballistic style of
weaponry. Unfortunately, this horrendous idea is true. Dates as far back as 1940
have shown that EM guns have been able to destroy cars, technical devices, and
live mammals just by the use of electromagnetism. Different wavelengths of EM
waves proved to create different effects for both cars and humans. And there
have even been reports of EM guns being used against countries. For example,
around the 1970?s a US embassy within Russia encountered a fire to one of the
tables in an office within the building and the cause was never found until a
certain scientist defected with another country and told his story. His story
entailed the Russians ?testing? their EM capabilities on a live target just
to ensure their technological advance. In short, EM guns and electromagnetism in
general pose a harmful threat to society for those people wish use it for the
wrong reasons. Further research on EM guns or gauss guns is given in detail by a
lot of work done by the University of Texas. Attached are points of contact and
a brief overview of the endless possibilities of this topic. The new wave of
weaponry exists in EM guns. The idea that a command post can destroy an armored
tank or vehicle from 5 to 10 miles away is too enticing to those who thrive off
the ideas of war. Or even the truth that that same command post can destroy a
whole army of soldiers by just waiving an invisible beam in their general
direction causing the soldiers to wallow and cry in pain because their bodies
hurt so much. The concept of electromagnetism is a wonderful subject and
beautiful art within itself. Unfortunately, like other things, when used the
wrong way even beautiful things have the capability to be turned ugly.
