摘　　要：磁致伸缩材料在换能器、传感器、致动器等领域具有广泛应用,因此对于高校理工科专业而言,磁致伸缩效应是电磁学课程教学中的重点内容.然而,磁致伸缩效应引起的形变小、现象不直观,同时,用于科研的测量设备体积大、价格高、不便携,因此,目前市场上尚无适用于课堂教学的磁致伸缩演示实验仪.本文基于迈克尔逊干涉仪原理,设计制作了磁致伸缩动态演示仪.其具有体积小、成本低、演示效果显著等优势,既可以用于学生较高层次的创新实验中,亦可用于课堂上磁致伸缩效应的演示.The magnetostrictive material has wide application fields for the transducer, sensor and actuator. Therefore, the magnetostrictive effect is the key content of electromagnetics to science and engineering majors in the college. However, the deformation caused by the magnetostrictive effect is small, the phenomenon is not intuitive, at the same time, the mea- suring equipment for research has large volume, high price. At present, there is no dynamic magnetostrietive demonstrator suitable for classroom teaching. This paper is based on Michelson interferometer principle, and the dynamic magnetostric- rive demonstration instrument has been designed. It has many advantages, such as small size, low cost, obvious demonstra- tion effect and so on. The instrument can be used in the higher level innovation experiments of students, and can also be used in the demonstration of magnetostrictive effect in class.
