Answer:
Magnetic permeability μ (Greek mu) is thus defined as μ = B/H. ... Magnetic flux density B is a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area.
μ₀ is the magnetic permeability. For finding its dimensions, Using the formula, c² = 1/μ₀ε₀, where c is the speed of light, ε₀ is the permmitivity of free space.
