Oersted

Oersted (abbreviated as Oe) is the unit of magnetizing field (also known as magnetic field strength or intensity) in the CGS system of units. The unit was established by the IEC in 1930 in honour of the Danish physicist Hans Christian Ørsted. The oersted is defined as 1000/4π (≈79.5774715) amperes per meter of flux path, in terms of SI units. The oersted is closely related to the gauss, the CGS unit of magnetic induction or magnetic field. In a v... more

Oersted (abbreviated as Oe) is the unit of magnetizing field (also known as magnetic field strength or intensity) in the CGS system of units. The unit was established by the IEC in 1930 in honour of the Danish physicist Hans Christian Ørsted. The oersted is defined as 1000/4π (≈79.5774715) amperes per meter of flux path, in terms of SI units. The oersted is closely related to the gauss, the CGS unit of magnetic induction or magnetic field. In a vacuum, 1 G = 1 Oe, whereas in a medium having permeability μ, their relation is G = μ Oe. One oersted also equals a magnetomotive force (mmf) of 1 gilbert per centimeter of flux path. less
