Answer» Solution :a. On the basis of magnetic properties, different materials are classified into i. DIAMAGNETIC substance, ii Paramagnetic substance and iii. Ferromagnetic substances. b. On the basis of magnetic properties , different materials and iii. Ferromagnetic substance . clue or ion does not posses any net magnetic moment of their own. These substances experience a very weak repulsive force in a magnetic field. e.g. Antimony , Bismuth, Copper , GOLD, Quartz, Mercury , Lead Water, Alcohol , Air, Hydrogen etc. Paramagnetic substances are those substances in which the individual ATOM or molecule or ion possesses a net NON - zero magnetic moment of their own. These substances experience a wea k attractive fore in a magnetic field. e.g. Alminium , Platinum , CHROMIUM , Manganese , Sodium , Copper chloride ,Crown glass , Liquid oxygen , Salt solutions of iron and nickel. Ferromagnetic substances are those substances in which each individual atom or molecule or ion possesses a non - zero magnetic moment . These substance experience a very strong force of attraction in a magnetic field . e.g. Iron, Nickel, Cobalt etc. c. Refer above |
