The invention discloses a magnetic testing device for a magnetic alloy material, which includes a testing assembly, the testing assembly includes a "匚" type mounting frame and a first electrode head, a second electrode head, and a Hall probe mounted on the mounting frame and a coil; the first electrode head and the second electrode head are installed on the top wall inner surface and the bottom wall inner surface of the mounting frame respectively; the coil is located between the first electrode head and the second electrode head; the Hall The probe is installed between the top wall and the bottom wall of the installation frame through a moving component, and can move up and down, forward and backward; the axis of the Hall probe is perpendicular to the axis of the first electrode head and the second electrode head; and the measuring instrument, the The measuring instrument is electrically connected with the first electrode head, the second electrode head, the Hall probe and the coil. A magnetic testing device for magnetic alloy materials disclosed by the invention adopts a Hall probe that moves back and forth up and down to realize the fixing and multi-directional adjustment of the Hall probe, so that the measurement result is more accurate.
Description
technical field [0001] The invention relates to the technical field of magnetic alloy material testing, in particular to a magnetic testing device for magnetic alloy materials. Background technique [0002] In the prior art, in order to ensure that the magnetic properties of the permanent magnet alloy meet the assembly requirements after heat treatment, it is necessary to measure its remanence Br and coercive force Hc. The commonly used method is to use different equipment to measure the coercivity Hc and remanence Br separately. The measurement method of remanence Br is: the sample is magnetized by a semiconductor silicon rectifier device, a magnetizing device composed of a ferromagnetic saturation AC voltage stabilizer and an electromagnet, and then a CST-18 magnetic measuring instrument is used to measure the α value, Through the formula Br=(α / 600*100000) / (S-cm 2 ) to calculate Br. The coercive force Hc is measured by measuring equipment consisting of a solenoid, a CD4...
