The Magnetic Characteristic Parameters Measuerment System Based On LabVIEW

With the development of electronics and computer technology,the application of magnetic materials has become increasingly widespread.There are so many kinds of magnetic materials with their own characteristics.Thus,how to measure magnetic properties of magnetic materials and apply different megnetic materials in appropriate areas to give full play to their effect have an extremely importance in modern society.It is not only in conformity with the rational allocation of resources,but also conforms to the strategic principle of sustainable development.The paper is based on the principle of magnetic flux measurement.With the help of LabVIEW development environment,the parameter measurement system of magnetic materials is realized.The measurement system can collect data,complete data processing and accurately display magnetization curves,demagnetization curves,magnetic energy product curves,magnetic hysteresis loops and characteristic parameters like remanence Br and coercive force Hc.The measurement system optimizes human-computer interaction design which is easy to operate.Not only the characteristic curves and characteristic parameters can be obtained directly,but also the collected data can be saved in a local file,which facilitates the comparison of multiple measurements and the subsequent reading.Finally,through two measurements of the same material,good reproducibility and accuracy of the measurement system are demonstrated.
