The oersted is the CGS unit of magnetic field strength, still widely used in the magnetic materials industry.
Named after Danish physicist Hans Christian Ørsted for his discovery of electromagnetism; it remained in industrial use after the shift to SI.
Measurement system: CGS system (non-SI, traditional unit). SI equivalent: 1 Oe ≈ 79.5775 A/m.
