The susceptibility of a magnetic material is $-2.6\times { 10 }^{ 5 }$. Identify the type of magnetic material and state its two properties.
Diamagnetic material.
Properties:
(i) They have the tendency to move from stronger to weaker part of the external magnetic field.
(ii) They expel magnetic field lines.
(iii) Such substances are repelled by a bar magnet.
(iv) When placed in an external magnetic field, a net magnetic dipole moment is developed inside it which is in a direction opposite to that of the applied magnetic field.
