Question

Which of the following figure represent the behaviour of diamagnetic substance in presence of external magnetic field?
(Note: Yellow dashed lines represents the direction of magnetic field)

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

When a diamagnetic substance is kept in a magnetic field, they are weakly repelled by an applied magnetic field. This happens because the diamagnetic substances are magnetised opposite to the direction of the applied magnetic field.
Thus, figure (a) represent the diamagnetic substance.
$H_{2}O,NaCl,KCl,C_6{H}_6,Ti{O}_2$ etc. are examples of diamagnetic substances.
