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 substances are attracted by an applied magnetic field.
C.
Magnetic moment of $$n$$ unpaired electrons is given by $$\mu = \sqrt {n\left( {n - 2} \right)} \,B.M.$$
D.
Magnetic moment increases as the number of unpaired electrons increases.
Answer :
Magnetic moment of $$n$$ unpaired electrons is given by $$\mu = \sqrt {n\left( {n - 2} \right)} \,B.M.$$
Solution :
$$\mu = \sqrt {n\left( {n + 2} \right)} \,B.M.$$
