The SI unit of magnetic permeability of free space is Tesla per Ampere (T A-1 m).
Explanation:
Magnetic permeability is a property of a material that describes its ability to allow magnetic lines of force to pass through it. In free space, which is a vacuum or empty space, the magnetic permeability is constant and is denoted by the symbol μ₀ (mu naught).
The SI unit of magnetic permeability is measured in Tesla per Ampere (T A-1 m). Let's break down the unit:
1. Tesla (T): It is the unit of magnetic field strength. One Tesla is defined as the magnetic field strength that will exert a force of one Newton on a one-meter wire carrying a one-Ampere current.
2. Ampere (A): It is the unit of electric current. One Ampere is defined as the flow of one Coulomb of charge per second.
3. Meter (m): It is the unit of length. In this context, it represents the distance over which the magnetic field is measured.
Therefore, the SI unit of magnetic permeability of free space is Tesla per Ampere (T A-1 m). This unit represents the ratio of the magnetic field strength to the electric current per unit length.
It is important to note that the value of the magnetic permeability of free space is approximately 4π × 10-7 T A-1 m. This constant is often used in calculations involving magnetism and electromagnetic phenomena.

Magnetic permeability of free space is a measure of the amount of resistance encountered when forming a magnetic field in a classical vacuum. The SI unit of permeability is weber ampere-1 metre-1 (Wb A-1 m-1) or tesla ampere-1 meter (T A-1 m).
