Magnetic permeability example
WebIf the ferromagnetic target material has a relative permeability smaller than 300, it does not mean that the back-bias arrangement will not work. It will only work with degraded performance. compared to a target with large permeability. For example, the maximum working air gap of the application could be reduced.
