Magnetic energy product (BH) in units of coke / m 3 (J / m3) or high • GOe 1 MGOe≈7. 96k J / m3
The product of B and H at any point on the demagnetization curve is called BH as the energy product and the maximum value of B × H is called the maximum energy product (BH) max. Magneto-energy product is one of the important parameters of the energy stored by the constant magnet. The larger the (BH) max, the larger the magnetic energy contained in the magnet. When designing the magnetic circuit, make the working point of the magnet be near the B and H corresponding to the maximum magnetic energy product as much as possible.
