discovery of magnetic history

Maxwell was born in Edinburgh, Scotland, in 1831. He developed an early teramatlah: at the age of fifteen years he has been able to present a scientific paper to the "Edinburgh Royal Society." He entered Edinburgh University and graduated from the University of Cambridge. Married but childless. Maxwell is generally considered the greatest theorists in the field of physics in the period between Newton and Einstein. His bright career ended too quickly because he passed away in 1879 due to attack cancer, not long after celebrating his birthday the 48.
Famous British physicist James Clerk Maxwell was well known through the formulation of four statements that describe the basic laws of electricity and magnetic. Both these areas before Maxwell was being investigated for a long time and have the same note there is a link between the two. However, despite the various laws of electricity and kemagnitan already discovered and contain the truth in some aspects, before Maxwell, none of those laws that constitute a unified theory. In he had four legal tools that are formulated in summary, Maxwell managed to describe precisely the behavior and mutual relations between electric and magnetic fields. By doing so he changed a large number of phenomena into a single theory that can be used as a handle. Opinion Maxwell has become fad in previous centuries, is widely both in theory and in practice science.
The most important value of, the new Maxwell's opinion is: a lot of general equations that can occur in all circumstances. All the laws of electric and magnetic pre-existing can be derived from Maxwell's opinion, as well as a large number of other law, which was once a theory that is not known. From Maxwell's opinion this could be shown how pergoyangan alternating electromagnetic field periodically is something that could happen. Movement back and forth like a pendulum is called electromagnetic waves, which when once driven will continue to spread outer space. From these opinions were able to show that the velocity of electromagnetic waves that reach approximately 300,000 kilometers (186,000 miles) per second. Maxwell knows that this is equal to the size of the speed of light. From this angle he rightly concluded that light itself consists of electromagnetic waves.
So Maxwell's opinion not only is the basic law of electricity and kemagnitan, but also it is also the basic law of optics. Indeed, all previous law known as the law of optics can be attributed to his opinion, too many facts and relationships with the things which was not revealed. Light visible to the eye is not only the type that allows electromagnetic radiation. Opinion Maxwell showed that electromagnetic waves other, in contrast to visible light by the eye in his wavelength and frequency, could have been there. These theoretical conclusions were remarkably reinforced by the Heinrich Hertz, who could produce and meet the two waves are visible by eye was predicted by Maxwell. A few years later Guglielmo Marconi demonstrates that the wave of the invisible eye that can be used for communication without wires, so what was his name menjelmalah radio. Now we use also for television, x-rays, gamma rays, infrared rays, ultraviolet light is an example of electromagnetic radiation. All of the ideas of Maxwell.
Although Maxwell's most prominent fame lies in his mind a great contribution in the field of electromagnetic and optics, he also gave a significant contribution to world science in other terms, including the theories of astronomy and thermodynamics (heat affairs investigation). One of particular interest is the kinetic theory of gases. Maxwell realized that not all gas molecules move at the same speed. Some slow, some fast and some incredible speed. Maxwell tries to specific formulas showed the smallest molecules to move at certain speeds as well. This formula is called the "spread of Maxwell," is the formula of the most widely used in scientific formulas and contains a meaning and important benefits in every branch of physics
