Abstract The paper is devoted to studying of estimations of scalar products of vector fields and their application in the proof of solvability for mathematical physics problems. The estimations of scalar products of vector field were proved in weighted functional spaces of summable functions. As an example of the application of such estimations there was proved the solvability for the problem of determination of stationary magnetic field in whole three-dimensional Euclidian space containing bounded conducting domain. The association between the proposed problem statement and the corresponding variational statement was shown too. There was investigated the possibility of determination of another unknown functions (electric field, volume density of electrical charge) inside the conducting domain.
