Oersted is a centimeter-gram-second (CGS) unit of the magnetizing field. It is equivalent to 1000/4π (≈79.5774715) amperes per meter of flux path. The term is named after Hans Christian Ørsted, the Danish physicist who discovered the connection between magnetism and electric current during one of his lectures. He discovered that a magnetic needle tended to align perpendicular to the current-carrying copper bar. Symbol: Oe.
