Based on the linearized magnetoelastic theory, analytical solution of the perturbed magnetic field in an infinite plate by a circular hole under extension and an external magnetic field was obtained in this paper. The results show that the perturbed magnetic field induced by mechanical deformations is 3 orders in magnitude smaller than the magnetic field without mechanical deformations 4 peaks and vales present for the perturbed magnetic field along the hole boundary, while only 2 peaks and vales present for a deformation-free magnetic field. It's also found that the intensity of the perturbed magnetic field decays very rapidly in the radius direction of the hole.
