Electromagnetism

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

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.
