InterviewSolution

1.	What is ferromagnestism ? Iron (Z = 26) is strongly ferromagnetic. Explain.
Answer» Solution :The substance containing large number of ELECTRONS can be permanently MAGNETISED, this property is CALLED as derromagnetism. `._(26)FE = [Ar] 3d^(6) 4 s^(2)` Iron consists of four unpaired electrons, HENCE it is strongly ferromagnetic.
