Before the humankind of the compass, man relied on the sun and the sky for direction when travelling. The concept of magnetic compact 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 force between magnets occurs without the magnets touching, it occurs a t a distance. When two magnets attract ther! e are in each early(a)s magnetic field. charismatic properties can be found in certain materials standardized 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 hold itself to iron if placed in close proximity to it. magnetic forces are produced by a motion of charged particles alike(p) electrons....If you want to get a full essay, order it on our website: OrderCustomPaper.com
