The make between magnets occurs without the magnets touching, it occurs at a distance. Whe n two magnets attract at that place are in ! each another(prenominal)s magnetic field. magnetic properties can be found in certain materials equivalent 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 up itself to iron if placed in close proximity to it. magnetic forces are produced by a motion of charged particles like electrons....If you want to get a full essay, order it on our website: OrderCustomPaper.com
