It is a magnet that retains its magnetism after removal of the magnetizing force.
Temporary Magnet
Electromagnet
Permanent Magnet
It is a discontinuity that lies deep within the object, however, may not disturb the lines of force sufficiently to cause them to emerge from the surface.
Internal Discontinuity
Surface Discontinuity
It refers to the continuous magnetizing of the parts simultaneously applying the inspection medium while the current is flowing.
Electromagnetic Field
Remanent Field
Continuous Field
It uses high frequency sound waves (typically in the range between 0.5 and 15 MHz) to conduct examinations and make measurements.
