Oersted is the unit of magnetic field strength in the CGS system of units. It is named after the Danish physicist Hans Christian Ørsted and is no longer valid since 1970 as an official unit.

Defines was an Oersted than the magnetic field strength at the acts dyn on a Einheitspol the power 1.

The unit Oersted has no exact equivalent in the SI unit system. But they can be expressed in amperes per meter. It is paid

Multiplying this by the magnetic field constant is obtained in vacuum, a magnetic flux density of 100 μT in the SI system of units and 1 Gs in the Gaussian CGS unit system:

The energy product of permanent magnets is often not provided in MGOe.
