On the basis of magnetic properties the substance are classified into three
a. What are these three classifications ?
b. Explain each of them
c. Give there examples for each .

Explanation

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
