In the October 2010 issue of the NDT Technician published by the ASNT (American Society of Nondestructive Testing), we have found a very interesting paper (1) that you may read.

It explains an MT technique using only one of the two legs of an AC hand-held electromagnet and which then produces a radial magnetic field.

For instance, we wrote a draft, titled “Quality of some calibration services” in May 2010, about … well … the quality of the calibration/verification of UV-A irradiance meters, luxmeters and magnetic field meters.
