These calculators are supplied to assist in choosing a design path. The calculator’s results should be viewed as “first-order” and not used as the primary data for product realization. They are based on the assumption that the magnet material exhibits a straight line demagnetization characteristic. There are many variables which exist in the real world and are not accounted for in these calculations. Please execute your due diligence when choosing a design path. Consult a Bunting Europe engineer for design path assistance.
