Abstract
If iron is the basis of the construction and transportation industries then iron magnetism is the basis of our civilization. Pieces of lodestone, suspended so they could turn were the first magnetic compasses and their importance to early navigation. William Gilbert in 1600 published his De Magnete and concluded that the Earth was itself magnetic and that this was the reason compasses pointed north. Ørsted in 1819 noticed the turning of a needle of a compass next to a wire carrying current. Since then magnetism became an important research topic that resulted in converting mechanical energy into electrical energy and vice versa
