About Oersted (Oe)

The CGS electromagnetic unit of magnetic field strength, defined such that 1 Oe = 1000 / (4Ο€) A/m β‰ˆ 79.5774715459 A/m.

History: Named after Hans Christian Ørsted, who discovered in 1820 that electric currents create magnetic fields.

Common Uses: Traditional magnetic recording media specifications, hard disk coercivity (Oe), and geophysics.

About Ampere per Meter (A/m)

The SI unit of magnetic field strength (H-field intensity), defined as the magnetic field produced at the center of a circular conductor of 1 meter diameter carrying a current of 1 ampere (1 A/m).

History: Formulated in classical Maxwell electromagnetism to express magnetizing force independent of medium permeability.

Common Uses: Electromagnetic compatibility (EMC) testing, coil magnetizing force calculations, and magnetic shielding design.
