Title:
ΔE MEASUREMENT DEVICE FOR MINIMIZING EXTERNAL MAGNETIC DISTURBANCE
Document Type and Number:
WIPO Patent Application WO/2011/071244
Kind Code:
A2
Abstract:
The present invention relates to a ΔE measurement device for minimizing an external magnetic disturbance, and more specifically, to a Δ E measurement device for measuring a change (Δ E) of Young's modulus in a magnetic field by using a magneto-acoustic resonance method and removing the bias effect caused by a geomagnetic field, magnetic equipment, and a magnetic apparatus. According to the present invention, a space for minimizing an external magnetic disturbance by using triaxial Helmholtz coils is provided, and the Δ E measurement device having a plurality of coil structures is inserted thereinto, thereby minimizing the external magnetic disturbance.
