Methods of magnetizing components and materials for magnetic particle inspection,for the use of permanent magnetism are limited; however, considerable ingenuity has been shown in the use of electric current as a source of magnetic induction. Among the reasons for the need for such ingenuity are the geometry and size of components, bars, sheets and billets of material and the fac

Sources of magnetic fields for magnetic particle inspection,be done by use of permanent magnets in some instances; however, satisfactory performance from such equipment is very restricted. In most applications the magnetic field is induced by use of some form of electric current. This may be by passage of current through the material as by use of a magnetizi

Procedures, specifications and documentation,le, and these aspects are discussed in sections 8.2 and 8.3. It must always be remembered that, along with other methods for non-destructive testing, magnetic particle inspection does not ‘fail safe’. If magnetic particle inspection fails to indicate a defect, that defect goes on to be incorporated

It is somewhat surprising that, in many cases, it is regarded as a separate process from manufacture rather than an integral part of the total manufacturing process. While most people seem to think of magnetic particle inspection and other test procedures as metho
