Paramagnetic substances have relative permeability_____________(a) Greater than 1(b) Less than 1(c) Equal to 1(d) ZeroI got this question in an internship interview.Origin of the question is Relative Permeability in chapter Simple Magnetic Circuits of Basic Electrical Engineering

Answer»

Right choice is (a) Greater than 1

To explain I would SAY: A PARAMAGNETIC material CREATES a magnetic field which is weakly ATTRACTED to that of the external magnetic field. Hence it has relative permeability greater than 1.
