Physics Question on Magnetism and matter
A diamagnetic substance is placed in a magnetic field of a bar magnet. Then it is
A
repelled by magnet
B
attracted by magnet
C
attracted by S-poles and repelled by N-pole
D
attracted by N-pole and repelled by S-pole
Answer
repelled by magnet
Explanation
Solution
Diamagnetic substances are feebly repelled by a magnet, when placed in a magnetising field they are feebly magnetised in a direction opposite to that of the field. This is due to negative susceptibility of diamagnetic substance.
