oersted

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. Abbreviation: Oe
2. (formerly) the unit of magnetic reluctance equal to the reluctance of a centimeter cube of vacuum between parallel surfaces. Abbreviation: Oe

noun

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

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 metreSymbol: Oe

n.

1. The centimeter-gram-second electromagnetic unit of magnetic intensity, equal to the magnetic intensity one centimeter from a unit magnetic pole.

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.

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.
