Question

Which of the following statements is not correct about magnetic behaviour of substances?

• A. Diamagnetic substances are repelled by an applied magnetic field.
• B. Paramagnetic substance are attracted by an applied magnetic field.
• C. Magnetic moment of n unpaired electrons is given by$\mu = \sqrt{n(n - 2)}B.M$
• D. Magnetic moment increase as the number of unpaired electrons increase.

Answer 1

Answer: (C)

Magnetic moment of n unpaired electrons is given by$\mu = \sqrt{n(n - 2)}B.M$

Answer 2

$\mu = \sqrt{n(n + 2)}B.M.$
