A crystal with a local plane defect in the external magnetic field $B$ oriented along the plane is investigated. Within the framework of the variational method a qualitative analysis of the degree of deformation depending on $B$ is carried out. It is shown that an increase of $B$ entails a more localized lattice distortion and its increase.
