摘要（英）：

The invention discloses a method for testing the piezomagnetic effect of iron-based amorphous alloy strip. The method includes the following steps: (1) preparing a testing apparatus: the testing apparatus in the testing includes a testing tube, an inductance coil which winds around the surface of the testing tube and a loading pressure head; (2) placing an alloy strip to the testing tube of the testing apparatus, using a sensor pressure head to apply stress on the alloy strip through a glass sheet; (3) gradually adding weight on the loading pressure head of the testing apparatus so as to apply pressure on the alloy strip; and (4) drawing a curve graph of the piezomagnetic effect value and a coil inductance. According to the invention, the apparatus used in the method is easy to manufacture and has low manufacturing cost; the material tested in the method saves the trouble of bonding lead, signal response is rapid, and the testing accuracy and stability are remarkable increased; the testing method is easy and simple to operate and has high sensitivity; and the result of the testing can directly and accurately reflect the piezomagnetic properties of the strip.
