Permanent Magnets Operating Temperatures

Permanent Magnets Operating Temperatures All Permanent Magnets experience variations in field strength (flux density) as the ambient temperature increases or decreases. How these variations in operating temperature influence magnetic strength depend on the type of magnetic material and the degree above or below ambient temperature in which they are expected to operate. The shape of [...]

Magnetic Measurements

Magnetic Measurements Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials [...]
