将霍尔元件应用于拉伸法测弹性模量实验，直接测量了微小位移．结果表明，霍尔元件在均匀梯度磁场中霍尔电压与微小位移有良好线性关系，采用拟合法计算得到钢丝弹性模量为1．96×1011 Pa ．

Hall element ,instead of optical lever ,was used to measure Young modulus of wire with stretching method . The micro-displacement was directly measured . The results showed that there was a good linear relationship between the Hall voltage and the micro-displacement when Hall element moved in a magnetic field of uniform gradient .The Young modulus of steel wire was meas-ured to be 1 .96 × 1011 Pa .
