Method to Measure wire Young's Modulus by Magnetic Induction Method

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.
