What elements effect the strength of a magnet?
It s the quality and percent of elements combined to make a particular grade of magnet material either in rod, bar or other custom shape. How and the type of magnetizer that is used is very important. Magnetizers can fully saturate or magnets can be calibrated to a desired strength. The type of magnetic path within a pickup is very important to how effective the magnetic field works between the strings and coil. When fully magnetized there is maximum alignment of the domains within each magnet. Magnets can become de-magnetized from several things such as heat when grinding, being hit with a metal object, AC current or transformers, time and environment. Another factor is size and shape of a particular magnet and it s proximity to another.
