|Oe the cgs unit of magnetic field strength; the field strength that would cause a unit magnetic pole to experience a force of 1 dyne in a free space. It is equivalent to 79.58 amperes per metre|
|[C20: named after H. C. Oersted (1777--1851), Danish physicist, who discovered electromagnetism]|
oersted oer·sted (ûr'stěd')
The centimeter-gram-second electromagnetic unit of magnetic intensity, equal to the magnetic intensity one centimeter from a unit magnetic pole.
|Oersted, Hans Christian 1777-1851.
Danish physicist who is credited as the founder of the science of electromagnetism. Oersted established the connection between electric current and magnetic force when he accidentally discovered that a compass's magnetic needle is deflected at right angles when placed next to a conductor carrying an electric current. The oersted unit of magnetic field strength is named after him.
