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 is the magnetic field if the magnetic intensity is 2 x 10³  A m^-1 ?

2 x 10^-2 A m^-1

Magnetic field : B = μ_ο μ_r H = μ_ο (1 + X) H

X = 2.7 x 10^-5 ; H = 2 x 10³  A m^-1

B = 2 x 10^-2 A m^-1
