oer·sted (Oe),

(er'sted),
A unit of magnetic field intensity; the magnetic field intensity that exerts a force of 1 dyne on a unit magnetic pole; equal to (1000/4π) A m-1.
[Hans-Christian Oersted, Danish physicist, 1777-1851]

oer·sted

(er'sted)
A unit of magnetic field intensity; the magnetic field intensity that exerts a force of 1 dyne on unit magnetic pole; equal to (1000/4π) A·m-1.

oersted

(ĕr′stĕd)
[Hans Christian Oersted, Danish physicist, 1777–1851]
A unit of magnetic field intensity. An oersted is the magnetism that exerts a force of one dyne on a unit magnetic pole. This term has largely been replaced by the SI unit amperes per meter.
