WebThe gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx /cm 2 or g / Bi /s 2, while the oersted is the unit of H -field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted. The units for magnetic flux Φ, which is the integral of magnetic B ...
