Science definitions for oersted

oersted

[ûr′stĕd′]

The unit of magnetic field strength in the centimeter-gram-second system. A unit magnetic monopole in a magnetic field with a strength of one oersted would be subjected to a force of one dyne. It is equal to 79.577 amperes per meter.

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.
