oersted

¹

[ ur-sted ]

noun

, Electricity.

1. the centimeter-gram-second unit of magnetic intensity, equal to the magnetic pole of unit strength when undergoing a force of one dyne in a vacuum. : Oe

[ ur-sted; Danish œr-stith ]

noun

1. Hans Chris·tian [hahns , kris, -tyahn], 1777–1851, Danish physicist.

oersted

/ ˈɜːstɛd /

noun

1. 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 Oe

Oersted

¹

1. 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.

²

/ ûr′stĕd′ /

1. 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.

From Seattle Times

Germany has other suppliers, and GasTerra and Oersted said they were prepared for a shutoff.

From Seattle Times

The time was ripe for a quantitative investigation of current induction, like that furnished by the genius of Ampère after the discovery by Oersted of the deflection of a magnet by an electric current.

From Project Gutenberg

He was born four years after Oersted made his famous discovery of the action of an electric current on a magnet, and two years before Ampère, founding on this experiment, brought forth the first great memoir on electromagnetism.

From Project Gutenberg

Oersted and Ampère, Henry and Faraday and Regnault, Gauss and Weber, had made discoveries and introduced quantitative ideas, which had changed the whole aspect of experimental and mathematical physics.
