In order to measure the temperature parameters of magnetic materials, in a process and an apparatus for measuring the characteristics of variation of magnetic induction of magnetic material with respect to temperature, a probe is provided at any one point A within the effective imaging range of an MR apparatus, the magnetic material to be tested also being provided at point A. The material is contacted directly with a heating unit, and a temperature sensor is attached to said magnetic material to be tested. The temperature control unit adjusts and controls the heating unit to heat the magnetic material to be tested based on the information collected by the temperature sensor. A processing unit of the MR system controls the probe at A in real-time and receiving the MR signals for feeding into the processing unit of the MR system, and the magnetic induction at A being obtained after the analysis of the system. The temperature parameter of the magnetic material to be tested is calculated by measuring the magnetic induction thereof at A under different temperatures.
