Magnetic material with a form factor of wire for experimentation and application in lower frequency electromagnetic devices such as motors and transformers promises gains in efficiency, lifetime, and manufacturing cost. The application of wire to magnetic components of transformers, motors, and other electromagnetic devices involves not only in some case drastic design changes but also necessitates some changes in the testing of wire magnetic components. First, let me point out that expensive test setups such as hysterigraphs (or hysteresigraph ) that derive hysteresis curves and data are the most viable and telling of the testing one can do, especially when variants of this testing allows for elevated temperature environment, DC characteristics and well as AC characteristics and various graphic depictions. That, to me, seems to be the best of the best. Variables can be accommodated and major parameters of magnetic qualities assessed all in one. But it is, done well, expensive and requires a completed product or a good representation of the completed product. I can rig up a system for displaying which can be used for relative comparisons but it is dependent upon my having near identical electromagnetic units to test else the setup must be changed and thus comparisons rendered will be suspect.
