Residual Magnetism in manufacturing: theory, definition and practical principles (physics)

In collaboration with an Industrial partner, there is a requirement to consider the fundamental principles of magnetics in order to place a new measurement technology, addressing the worldwide issue of residual magnetism, on a firm scientific footing. Your research will be pivotal in producing the definitive reference body of work, concerning theory, definition and practical principles, in this new technique of magnetic measurement.
Advanced manufacturing is dependent upon even tighter mechanical tolerances, in some cases +/- 0.25 microns, which is impossible if magnetic contamination is present. It is therefore necessary to control residual magnetism levels to avoid contamination through ferrous particles. Current high-tech manufacturers in aerospace, medical, automotive and other industries face a problem; they lack theoretical understanding and valid measurement techniques. The introduction of a new technology capable of accurately measuring residual magnetism requires a scientific basis for practical measurement procedures.
The research project will produce a clear theoretical understanding of the physics involved, defined units of measurement, as well as practical techniques and validating the new instrumentation techniques currently in development. In doing so, we aim to alleviate real and growing problems in worldwide advanced manufacturing technologies.
