We have studied the magnetic field effects on the diamagnetic susceptibility and binding energy of a hydrogenic impurity in a Inhomogeneous Quantum Dots by taking into account various geometries of these systems like spherical, cylindrical and cubic inhomogeneous Quantum Dots. The calculation was performed with the use of a variational method in the effective mass approximation. We describe the effect of the quantum confinement by an infinite deep potential. In order to make a comparison of the geometry, the results obtained for these tree structures show that the diamagnetic susceptibility and the binding energy is proportional with the magnetic field and strongly depend on the position of the donor. There is more pronounced for the large spherical layer.
