Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT) is a nondestructive testing (NDT) method which is used for locating surface or near surface discontinuities in ferromagnetic materials. Magnetic particle testing is based on the principle that magnetic lines of force will be distorted by a change in material continuity; i.e., a discontinuity creating a magnetic field or flux leakage.
A test object is magnetized by passing an electric current through the object (direct magnetization) or by placing it in a magnetic field (indirect magnetization). The electric current creates a magnetic field perpendicular to the current flow. For this reason, magnetic fields are applied in at least two directions, perpendicular to each other, to assure the examination areas are completely evaluated.
When the magnetic field has been established within the test object, magnetic particles are applied to the surface to be examined. They can be dry or suspended in a liquid. Discontinuities can be further enhanced using fluorescent magnetic particles and observing them under black light. After removal of excess particles, the magnetic flux leakage field at a detectable discontinuity reveals its location, shape, and size.
