* Transverse and axial type
* Hall Probe and Search coils
Reference magnets generate a homogeneous magnetic field in an air gap. They are mainly used to calibrate sensors for the magnetic field strength H or the magnetic flux density B. For example Gaussmeters, Teslameters or field strength measuring coils (search coils) can be calibrated using reference magnets.
Reference Magnets VM 4
The transverse reference magnets VM 4 are available with different flux densities in a range from about 0.01 T to 1 T (0.1 kG to 10 kG).
One model, which stands out in the product range, is the reference magnet VM 4 - 10 mm. It is designed for maximum accuracy and generates a flux density of 0.25 T in an air gap of 10 mm height. The homogeneity of the magnetic field in the air gap is so good that the calibration of the system can be carried out directly by a nuclear magnetic resonance (NMR) measurement.
The reference magnets VM 4 - 2 mm and VM 4 - 5 mm have tapered pole caps.
