Question

State whether true or false:

Relative permeability and absolute permeability have the same units.

• A. True
• B. False

Answer 1

The correct option is B False

Answer is B.

In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. Hence, it is the degree of magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the Greek letter $\mu$.
Relative permeability:
Relative permeability ${\mu }_r$, sometimes denoted by the symbol r, is the ratio of the permeability of a specific medium to the permeability of free space.
Absolute permeability:
The ratio of the magnitudes of magnetic flux density $\overrightarrow{B}$, to the intensity of the magnetic field in a medium $\overrightarrow{H}$
$\mu =\frac{B}{H}$; it's measurement is in Wb./Amps.m.
Therefore, the units of Relative permeability and Absolute permeability are different.
