Magnetization is possible of certain materials, it is possible to find out discontinuities by using a medium (iron powder) having the magnetic attraction. Magnetic Particle Inspection is relatively easy and simple test method that can be applied at various stages of manufacturing and process.
The direction is more impartment factor than the magnitude of magnetizing current. For reliable inspection, magnetic lines should be perpendicular to the discontinuity. If magnetic lines are parallel to the discontinuity then leakage will be little and an indication will be small or indefinite.
Cracks distort the magnetic lines of force and create poles on either side of the crack. Strength depends on upon the number of interrupted lines of force. An indication of maximum size is found when magnetic lines are at right angle to the discontinuity. The Intensity of magnetization depends upon the susceptibility of the material to become magnetized
