Question:

Which of the following is true for a paramagnetic substance ?

Options:

\(\mu\)r = 1

\(\mu\)r = 0

\(\mu\)r > 1

\(\mu\)r = \(\infty\)

Correct Answer:

\(\mu\)r > 1

Explanation:

Paramagnetic substances have tendency to pull magnetic field lines when placed in magnetising field.

$\mu_r = 1+ X $

For para magnetic substances X has small positive value. So for paramagnetic substances $\mu_r > 1$
