A substance whose relative permeability is less than the permeability of free space is?(a) Diamagnetic(b) Paramagnetic(c) Ferromagnetic(d) Not a magnetic substanceThis question was posed to me in an interview for job.I need to ask this question from Relative Permeability in division Simple Magnetic Circuits of Basic Electrical Engineering

Answer»

Right CHOICE is (a) DIAMAGNETIC

The explanation is: A diamagnetic material creates a magnetic FIELD opposing that of the external magnetic field and it repels the external magnetic field. Hence its relative permeability is less than that of the free space.
