Magnetic flux density - adjustment aid

10 Appendix
10.1 Magnetic flux density - adjustment aid
Depending on the material used, the thickness of workpieces and the measuring instrument used, the
winding numbers or current values may vary. Ideally, the measured flux density should be in the middle of
the parameter field.

[1] Example of use:
The measured value is 25 mT. This results in a number of turns of 9 and a degaussing current of 175
A if the activgauss process is used.
