Hint: Permeability is defined as the measure of magnetization that a material possesses to the applied magnetic field. It is denoted by $\mu .$

Complete step by step solution:
Given data:
Magnetizing field, $H = 360A{m^{ - 1}}$
Magnetic flux density, $B = 0.6T$
Permeability =?
We know that Permeability is given by the formula,
$\mu = \dfrac{B}{H}$ where B is the magnetic intensity and H is the magnetizing field
$\Rightarrow \mu = \dfrac{{0.6}}{{360}} = \dfrac{1}{{600}}Tm{A^{ - 1}}$
Thus the permeability $\mu = \dfrac{1}{{600}}Tm{A^{ - 1}}$.

Hence the correct option is C.

Note: 1. The number of magnetic field lines passing through the given closed surface is called Magnetic flux. It is denoted by $\varphi$ and the unit is Weber. The magnetic flux indicates the strength of magnetic lines that are produced by a magnet.
