Unique magnetic processing

There are many challenges when magnetizing magnetic materials and building them into devices and assemblies. Flux generating permanent magnets, magnetically-soft flux carrying components, and frequently a combination of the two, must routinely be processed and assembled to achieve a specific end result. Various material characteristics and interactions may prevent the magnetic flux from going where it is needed and/or reduce its amplitude to an inadequate level to achieve the required result. This paper describes some problems that are commonly encountered in the process of building magnetic devices and offers insights into how they can be dealt with in practice. Some examples of actual products are discussed.
