Temperature constraints and methods of magnetization
Maximum operating temperature for ceramic magnets is 250°C. Although you will experience magnetic losses when operating at elevated temperatures, the losses are recovered when the material is brought down to normal ambient temperature. However, operating in very cold temperatures (-20°C) can result in permanent losses of magnetic strength unless the circuit has been designed for such extremes. Magnetization: ceramic magnets must be magnetized in the direction of orientation, which is the same as the direction of pressing.
