  1. 1. Materials can be classified as magnetic non-magnetic magnets can be attracted by cannot be attracted by are of two types temporary magnets permanent magnets made by using 1 stroking with a magnet 2 a solenoid carrying a direct current, d.c. have these properties 1 attract magnetic materials 2 have two poles, North Pole and South Pole, which 3 attract unlike poles but repel like poles 4 produce magnetic fields 1 heating 2 hammering 3 using a solenoid an alternating current, a.c. lose their magnetism
