The magnetic properties of a ferromagnetic material change with the change of temperature. When the temperature rises to a certain value, the material will transit from ferromagnetic state to paramagnetic state. This temperature is called Curie temperature. Determining the curie temperature of ferromagnetic materials is not only of great significance to the research and development of magnetic materials and magnetic devices, but also to the applications of engineering technology.
1. Measure the hysteresis loop of soft magnetic ferrite material; acquire the coercitive force and residual magnetism of the material;
2. Measure the basic magnetization curve of soft magnetic ferrite and the relationship curve between magnetic conductivity and magnetic field strength;
3. Measure the Curie temperature of the ferromagnetic material.
