Scope

This standard is applicable to the measurement of the basic magnetization curve and magnetic parameters on the hysteresis loop of ring samples made of soft magnetic alloys (iron-nickel, iron-cobalt vanadium, iron-aluminum alloys, etc.) at room temperature: magnetic induction Strength B, magnetic field strength H, magnetic permeability μ, residual magnetic induction B, coercive force Hc, squareness ratio B, /Bm. When the measurement error is not greater than that, other measurement methods are allowed.
