Efficient magnet charging and conditioning

The authors discuss energy storage/capacitor discharge instrumentation only, because this form of processes equipment can be upgraded to excessive energy levels much more easily than DC electromagnets and half-cycle units can. The data used are the result of four decades spent in designing, using and observing magnet processing systems. Most information has been gleaned from empirical studies and results. A re-evaluation of magnet processing instrumentation prompts the investigation of matching the processing fixture to the instrument for optimum energy transfer. Factors which must be considered in designing or specifying a magnetizer or conditioner are: the magnet material and its coercive force; the size of the entire magnet assembly; the location of the magnet in the assembly; the type and size of the assembly materials other than the permanent magnets; the polar configuration of the assembly; and production speed required.
