The magnetic permeability '\(\mu\)' a of a paramagnetic substance is :
- A \(\mu=1\)
- B \(\mu=0\)
- C \(\mu>1\)
- D \(\mu\) is infinite
Answer & Solution
Correct Answer
(C) \(\mu>1\)
Step-by-step Solution
Detailed explanation
The magnetic permeability \(\mu\) of a material is related to its relative permeability \(\mu_{r}\) by the relation \(\mu = \mu_{0} \mu_{r}\). For a paramagnetic substance, the magnetic susceptibility \(\chi\) is small and positive. The relative permeability is given by…
