Question

Which one of the following is not a characteristics of diamagnetism?

• A. The diamagnetic materials are repelled by a bar magnet
• B. The magnetic susceptibility of the materials is small and negative
• C. The origin of diamagnetism is the spin of electrons
• D. The material move from a region of strong magnetic field to weak magnetic field

Answer 1

Answer: (C)

Diamagnetic substances are repelled in an external magnetic field, ie, have a tendency to move from high to low field region. Their magnetic susceptibility is low and negative. Explanation of magnetism of diamagnetic substances can be given on the basis of orbital motion of electrons.
