Magnetism

Magnetism Essay Magnetism has been known to human beingskind for everywhere gram years ago. Basically Chinese and Greeks spy many exalted stones that were metal. About 4000 years ago, rocks were found in old-fashioned Greek province of Magnesia. Also, Chinese mariners utilize metals to navigate. These rare metals were called lodestones. Chinese mariners spy that if lodestones were stroked, a steel needle will set sexual union and south. This was how the opinion of a magnetised orbit was common to man. The magnetic reaching was so popular that it was use by Christopher Colombus when he crossed the Atlantic Ocean. Chinese innovators used the magnetite as a part of a turn of events made of dressed-up brass. On its surface a spoon-shaped lodestone was free to spread in the direction of the magnetic field. The compass marks mans earliest step to the counterbalance application of magnets. A compass needle determines direction by aligning itself with macrocosms magneti c North game and South Pole. By 13 century A.D. the compass changed its fillet of sole purpose and was near to man when travelling the sea. Before the origination of the compass, man relied on the sun and the sky for direction when travelling. The concept of magnetism continue to be popularized and around 1600 William Gilbert discovered that Earth was a big magnet itself.

Understanding magnetism was long foregone since it has been unexplained. There are many unrequited questions about magnetism e.g. What is it caused by? How it works exactly? The take out between magnets occurs without the magnets touching, i t occurs at a distance. When two magnets att! ract thither are in each another(prenominal)s magnetic field. magnetic properties can be found in certain materials comparable iron, cobalt and nickel. When a material has magnetic properties it is attracted to iron, iron alloys and other magnetic materials. An physical object with magnetism will tie itself to iron if placed in close proximity to it. magnetised forces are produced by a motion of charged particles equivalent electrons....If you want to get a full essay, order it on our website: OrderCustomPaper.com
