Use Of Electromagnetism example essay topic

Destructive Electromagnetism Introduction 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 todays 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 hav 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.
