Question: Using the magnetization characteristics for neodymium-iron-boron given in figure find the point of maximum-energy product and the corresponding flux density and magnetic field intensity, using

Using the magnetization characteristics for neodymium-iron-boron given in figure find the point of maximum-energy product and the corresponding flux density and magnetic field intensity, using these values, repeat Example 1.10 with the Alnico 5 magnet replaced by a neodymium-iron-boron magnet. By what factor does this reduce the magnet volume required to achieve the desired air-gap flux density?
