Book 1993from improvements in instrumentation which has made the measurement of peak values of time varying currents practicable. The major changes have arisen from health and safety and environmental concerns. These involve chemicals and exposure of personnel to air-borne electromagnetic fields and long wav

Basic electromagnetic field theory, which are not widely understood. It must be remembered that while this mathematician’s playground produces a large number of vital results describing fields in their general form, parts of the field and even specific points in the field, the equations and calculations are mathematical expressions of physical effects.

The history and basis of the magnetic particle testing method,oke discovered that they coincided with patterns of defects in the surface. In the following 20 years, the foundations of the magnetic particle inspection method of non-destructive testing were laid down. Many people on both sides of the Atlantic Ocean contributed to these firm foundations on which the modern application of the method is built.

Equipment for magnetic particle inspection,ng components which are unusually large or which present special problems for magnetization, and throughput is not a serious problem. Standard types of equipment are discussed in section 10.2 and special equipment in section 10.3. There is too a need for special options and accessories in many applications and these are dealt with in section 10.4.
