Question 42 of 57
Given below are two statements :
Statement - I : Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement - II : Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
Choose the correct answer from the options given below
Show answer and solution
Answer: (A) Both Statement - I and Statement - II are true.
Statement-I is true as susceptibility of ferromagnetic and paramagnetic materials is inversely related to temperature, so it increases with decrease in temperature.
Statement-II is also true as because of orbital motion of electrons, the diamagnetic material is able to oppose external magnetic field. Once an external magnetic field is applied, diamagnetic materials develop an induced magnetic field opposite to this field and thus are repelled by the field.
