Question

What is formula of Magnetic Field

Answer 1

Magnetic Field Formula. The magnetic field formula contains the constant^{\mu_{0}}. This is known as permeability of free space and has a value^{\mu}_{0} = 4\pi \times 10^{-7} (T \cdot m/ A). Besides, the unit of a magnetic field is Tesla (T).

Answer 2

Answer:

B = μ02πr

Explanation: B= magnetic field magnitude

                      μ0=permeability of space

                      r = distance in meters
