Which among the following has a relative permeability much larger than 1?(a) Diamagnetic materials(b) Ferromagnetic materials(c) Paramagnetic materials(d) Ferrimagnetic materialsThe question was posed to me in unit test.This interesting question is from Permanent Magnets and Electromagnets topic in portion Magnetism and Matter of Physics – Class 12

Answer»

The correct choice is (b) Ferromagnetic materials

The EXPLANATION: The relative permeability of ferromagnetic materials is much LARGER than 1. Ferromagnetic substances are those, which when PLACED in a magnetic field are strongly magnetized in the DIRECTION of the magnetizing field, i.e., it is strongly attracted by a magnet.
