In the model of a zero‐radius potential the equation for the bound state in magnetic and electric fields is obtained. The electric field F is directed normal to the surface of a dimension‐limited system, and the magnetic field is directed along the axis of the spatial quantization or along the surface of a parabolic quantum well (QW). The dependences of the binding energy (BE) on the magnetic field H , thickness of the QW, position of impurity in the QW and direction of the electric field F have been investigated. It is shown in particular that the BE increases with the increase of H , and the energy of a localized state decreases with increase of F . The results are compared with BE, obtained with the use of the variational method.
