Measurement of magnetic susceptibility of discrete samples versus field and/or frequency. The original manual operation has been replaced by a simple (currently experimental) stepping motor controlled automation.
NOTE: The mains frequency (Germany: 50 Hz) and its multiples have to be avoided! Thus, useful frequencies are f = n*50+25 Hz.
