Permanent magnets come in different shapes and sizes.  B. Magnetic Material A material which is attracted by a magnet is called a magnetic material. Iron is a magnetic material and also steel, nickel and cobalt (most of steel are also magnetic). Nowadays many small and strong magnets are made using neodymium . Authors metal such as aluminium and tin are non-magnetic. C. Magnetic Poles Magnets attract magnetic material because there is a magnetic force which pulls magnetic object when magnet attracts it. The ends of the magnet are called its magnetic pole . The poles are called the north pole(N) and the
