What is the correct order of magnetic strength among the following elements?

a) Fe > Co > Ni > Cu

b) Fe > Ni > Co > Cu

c) Cu > Ni > Co > Fe

d) Cu > Fe > Ni > Co

Expert Solution

Answer : a) Fe > Co > Ni > Cu

Explanation :

Magnetic strength of the element depends on the no.of unpaired electron present in its shell.

The more unpaired electron the more Magnetic strength.

Iron(Fe) have 4 unpaired electrons.
Cobalt have 3 unpaired electrons.
Nickel have 2 unpaired electrons.
Copper have only 1 unpaired electron.

Hence, the correct order of magnetic strength is: Fe > Co > Ni > Cu.

a) Fe >Co > Ni > Cu
