Choose the Optimum Magnet Grade: Know Why Magnets Demagnetize
In the absence of external influences, a commercially viable magnet alloy should remain magnetic for hundreds of years. The alloy’s resulting field may degrade slightly from aging effects, but for the most part it should remain an effective magnetic field source. With that said, most magnets used in real world applications experience many external demagnetizing conditions. A partially demagnetized magnet may greatly impact operational performance that may result in failures in the field…
