The magnetic induction that remains in a magnetic circuit after the removal of an applied magnetizing force. If there is an air gap in the circuit, the remanence will be less than the residual induction.
Also called retentivity.
Magnetic Hysteresis Loop
This should not be confused with residual flux density. If the magnetic circuit has an airgap, the remanence will be less than the residual flux density.
Remanent-flux Density Br
The residual magnetism of flux density (Br) remains in the iron core after the external magnetic field strength (H) is removed.
