Among the following properties describing diamagnetism identify the property that is wrongly stated
1 Diamagnetism is explained by Weber theory.
2 Diamagnetic material does not have permanent magnetic moment.
3 The magnetic moment of individual electrons neutralise each other.
4 Diamagnetic materials have a small positive susceptibility.
Explanation:
Susceptibility of diamagnetic substance is negative and it does not change with temperature.

Assertion : In water, value of strength of magnetic field decreases. Reason : Water is a diamagnetic substance.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Water is a diamagnetic substance, and its magnetic susceptibility is less than one (but more than zero) When placed in an external magnetic field feebly diamagnetic substances (like water), they repel the magnetic field, causing a decrease in the strength of the magnetic field within the material. The value of the magnetic field decreases when water is exposed to a magnetic field. So correct option is (1).
