Question:

Read the passage and answer the question.

The magnetic susceptibility of a substance is defined as the measure of how readily it responds to an external magnetic field. It gives the measure of a substance's aptness to acquire magnetism. It has no units. Mathematically, it is defined as the ratio of the intensity of magnetization to the magnetic intensity. The susceptibility of a substance is given as (2.7 x 10-5). 

What type of magnetic material is this substance?

Options:

Paramagnetic

Diamagnetic

Ferromagnetic

Antiferromagnetic

Correct Answer:

Paramagnetic

Explanation:

The susceptibility is small and positive. Thus, the substance is paramagnetic.
