FROM THE THREAD LINK - A new type of magnetic field detection system, which can operate at a frequency below 1 kHz, is proposed and developed. The system consists of a 40-turn-coil to generate the magnetic field and a magneto resistive sensor to detect both the amplitude and the phase signal of the magnetic field induced by eddy-current and magnetization of the samples. The magnetic field detection of ferro- and non-magnetic samples using the system is demonstrated and discussed.
There you go my special needs buddy, SAMPLE, come on now you say it, SAMPLE. WELL DONE, these tests are carried out in a uni lab, no long distance across location. Because these are done in a class room with a SAMPLE.
If you do not understand what a SAMPLE is please reply back and i will spend some more time with my special needs buddy.
kind regards and happy prospecting
