MULTIDIRECTIONAL MAGNETIZATION Multidirectional magnetization uses several contact points and relay switches to produce constantly varying magnetic fields. Typical uses of multi directional magnetization are…
Read articleThe following characteristics affect key test parameters, including required magnetizing current, current on time, when to apply particles and demagnetization requirements. 1. Alloy, shape…
Read articleA circular magnetic field is induced into a test object either by passing magnetizing current directly through the test object (direct magnetization), or by…
Read articleSURFACE DISCONTINUITIES The magnetic field surrounding subsurface discontinuities drops off very rapidly with distance below the surface. Magnetic particle movement is critical to the…
Read articleThe magnetic field surrounding a permanent bar magnet has polarity. As an example, the Earth itself can be considered a bar magnet because of…
Read articleWhen an external magnetic field is applied to ferromagnetic materials, the magnetic domains align parallel to the applied fields. These domains are very small,…
Read articleThe theory of magnetic fields indicates that an object is magnetized when part or all of its atomic elements have their north and south…
Read articleCAPABILITIES OF MAGNETIC PARTICLE TESTING Magnetic particle testing can reveal surface discontinuities, including those too small or too tight to be seen with the…
Read articleMagnetic particle testing can detect both production discontinuities, such as seams, laps, grinding cracks and quenching cracks, and inservice damage, such as fatigue and…
