- The magnitude of the magnetic field can be calculated using the formula B = frac {mu_0 I} {2 pi r}1. Here, B is the magnetic flux density, I is the current magnitude, r is the distance, and mu_0 is the permeability of free space1. The unit of magnetic field is Tesla (T)2. Magnetic field intensity is measured in units of amperes/metre and is given by the formula H = B μ − M3. The magnitude of the magnetic force can be written as F = qvBsin {theta}4.
