Contrary to what others believe, I do age magnets physically and visibly. I quote from Dean of Technology Lester R. Moskowitz, registered professional engineer and author of “The Permanent Magnet Design and Application Handbook. “Fortunately, modern Alnico and Ferrite materials are metallurgically stabilized by aging at the mills and are generally very stable.” He lists one environmental factor as time, and a method of stabilization as “Partial demagnetization (or) magnetic aging.” “Aging can also occur with temperature, mechanical stress and external magnetic fields.” I would suggest to those who would like to learn or need to learn about magnets: go to the library and read books on the subject.

Many manufactures have different procedures for making products, and I have developed many of my own components to cut, calibrate, grind and magnetize our designed magnets. I visibly age my coils and magnets with procedures developed over the years also know as “Environmental Effects”. This is a scientific fact!
