1. What is a high-precision hysteresis dynamometer?

The high-precision hysteresis dynamometer is an instrument for measuring magnetic field performance. It can measure the magnetization curve of materials under different magnetic field strengths and analyze the magnetic field performance of materials based on the measurement results.

2. Working principle of the high-precision hysteresis dynamometer

The working principle of the high-precision hysteresis dynamometer is based on the hysteresis effect. When a material is subjected to a magnetic field, the magnetic moment of the material changes, resulting in hysteresis phenomena. The high-precision hysteresis dynamometer infers the hysteresis performance of materials by measuring the magnetization curve of materials under different magnetic field strengths.

The high-precision hysteresis dynamometer typically consists of an electromagnet, circuit system, controller, and computer. The electromagnet is used to generate the magnetic field, the circuit system controls the current of the electromagnet, the controller manages the circuit system and computer, and the computer processes and analyzes the measurement data.

4. Measurement principle of the high-precision hysteresis dynamometer

The high-precision hysteresis dynamometer infers the hysteresis performance of materials by measuring the magnetization curve of materials under different magnetic field strengths. During the measurement process, the sample is first placed in the magnetic field, and then the magnetic field strength is varied to measure the magnetization curve of the material. Finally, by analyzing the magnetization curve, the hysteresis performance of the material can be obtained.

5. Applications of the high-precision hysteresis dynamometer

The high-precision hysteresis dynamometer is widely used in fields such as materials science, energy research, electric power industry, electronics industry, and computer industry. For example, it can be used to test the hysteresis loss of motor core materials, test the magnetism of disk materials, and test the hysteresis loops of certain materials.
