Question

Which one of the following, when suspended freely, slowly sets itself parallel to the direction of the magnetic field?

(a) Ferromagnetic materials

(b) Diamagnetic materials

(c) Paramagnetic materials

(d) Ferrimagnetic materials

I have been asked this question in exam.

Origin of the question is Permanent Magnets and Electromagnets in division Magnetism and Matter of Physics – Class 12

Answer 1

Right answer is (c) Paramagnetic materials

For explanation: Paramagnetic materials are those when suspended freely inside the magnetic field, it slowly sets itself parallel to the direction of the magnetic field. When placed in a non-uniform magnetic field, it tends to move from weaker to a stronger magnetic field.
