Question

The S.I. unit of magnetic permeability is

• A. $\frac{A}{m}$
• B. $\frac{A}{m^2}$
• C. $\frac{H}{m}$
• D. $\frac{H}{m^2}$

Answer 1

The correct option is C

$\frac{H}{m}$

Definition of Magnetic Permeability: Magnetic permeability is a constant of proportionality between magnetic induction and magnetic field intensity.

S.I. unit of Magnetic Permeability: The S.I. unit of magnetic permeability is henries per meter.

Thus, the S.I. unit of magnetic permeability is henries per meter $(H{m}^{-1})$.

Hence, option C is correct.
