O
oersted
The unit of magnetic field strength in the unrationalized centimeter-gram-second (cgs)
electromagnetic system. The oersted is the magnetic field strength in the interior of an elongated,
uniformly wound solenoid that is excited with a linear current density in its winding of`1
abampere per 4 centimeters of axial length.
offline
