Which, among the following, have positive susceptibility?

(a) Diamagnetic

(b) Paramagnetic

(c) Ferromagnetic

(d) Both paramagnetic and ferromagnetic

I had been asked this question during an online interview.

My doubt stems from Permeability of Free Space or Magnetic Constant topic in section Simple Magnetic Circuits of Basic Electrical Engineering

The correct choice is (d) Both paramagnetic and ferromagnetic

To explain: Magnetic susceptibility is the degree of magnetisation of a material in response to the external magnetic field. Both paramagnetic and ferromagnetic materials have positive susceptibility as they get magnetise when placed in external magnetic field.
