根據霍爾器件能構成均勻的腔體磁場，提出了一種用磁感應法測量金屬絲楊氏模量的方法。通過導磁鐵微移動影響腔體磁路變化確定了霍爾電壓與位移函數的關系，計算出了K值。最后將其與拉伸法測量金屬絲楊氏模量的兩種測量方法結果值進行了比較：在霍爾器件靜態輸入-輸出特性下，所測楊氏模量有較大改善。

Abstract The uniform cavity magnetic field can be formed by Hall device. This paper presents a method to measure the wire Young’s modulus by means of a magnetic induction approach is presented. Guide magnet small displacement influence is passed to change on distribution of carity magnetic field. The relationship between Hall voltage and displacement function is determined. K value is calculated. Finally, a comparetion between the measurement result values by the methods of magnetic induction and stretch is also made. The measured of Young’s modulus has improved greatly under the imput-output characteristic in Hall device.
