Before the population of the compass, man relied on the sun and the sky for direction when travelling. The concept of magnetic attraction 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 unreciprocated questions about magnetism e.g. What is it caused by? How it works exactly? The advertise between magnets occurs without the magnets t ouching, it occurs at a distance. When two m! agnets attract thither are in each early(a)s magnetic field. magnetic properties can be found in certain materials wish 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 make up itself to iron if placed in close proximity to it. magnetized forces are produced by a motion of charged particles desire electrons....If you want to get a full essay, order it on our website: OrderCustomPaper.com
