W-BH-I type magnetic material hysteresis loop and magnetization curve tester Introduction: The basic magnetic properties of magnetic materials are characterized by hysteresis loops and magnetization curves. Ferromagnetic materials with various characteristics are widely used in industries, transportation, communications, electrical appliances and other fields. Therefore, the measurement of the basic properties of magnetic materials is very important in practice and college physics experiments, and has been included in the physical experiment syllabus of various domestic colleges and universities. TW-BH-I magnetic material hysteresis loop and magnetization curve tester has the following advantages: characteristic: 1. The high-precision digital Tesla meter is used to directly measure the magnetic induction intensity in the small gap of the magnetic circuit of the material, and the measurement accuracy is high. 2. When measuring the DC magnetic properties of materials, the samples were demagnetized and magnetized to increase the opportunities for students to learn the basic concepts of magnetism and hands-on operation. 3. Because a small parallel gap is opened for the rectangular sample, it is convenient for students to measure the magnetic induction intensity distribution in the gap. Moreover, the calculation of the magnetic field strength (including the correction introduced by the gap) has further deepened the understanding of the ampere circuit law. 4. This instrument provides three different magnetic materials for experiments to expand students' understanding of the magnetic properties of various typical materials. In view of the above advantages, the learning content of this instrument is rich and the focus is outstanding. Therefore, it has more teaching and practical value than traditional impulse galvanometer method and capacitor integrator dynamic method. This instrument can be used in basic physics experiments and design open physics experiments in colleges and secondary vocational schools. Experiment content: 1. Use a digital Tesla meter to measure the relationship between the magnetic induction intensity B of the remanence in the magnetic sample and position X, and measure the uniform range of the magnetic induction intensity along the X direction. 2. Learn the demagnetization of the magnetic sample to be measured, and measure the initial magnetization curve and hysteresis loop of the sample. 3. Learn the application of ampere loop law in magnetic measurement. Technical parameters: 1. Digital Tesla meter four and a half LED display, measuring range 0-2T; Resolution 0.1mT; With Hall probe 2. Digital constant current source four half LED display, current range 0 － 600.0mA, continuously adjustable 3. Magnetic material samples (3 kinds of samples) have a strip rectangular structure with a section length of 2.00cm; Width 2.00cm; Clearance 2.00mm
