Following the M.Faraday`s hypothesis, the gravitational field is considered as a viscous-elastic body, which is characterized by a number of properties: modulus of elasticity, viscosity, anisotropic structure, the ability to shear deformation. Rotation and movement of the body in orbit are leading to periodic shear deformation of the field, which is implemented in the form of gravitational radiation. Two equations are suggested to define the speed of its spread. Velocity gradient at the field shear causes concentric orientation of the power lines at which the motion of orbiting bodies takes place without energy consumption. Distance to the orbits with the orientation of force lines obeys the quantum law. The hypothesis on the origin of the magnetic field by the motion of celestial bodies and the shear deformation of the gravitational field is suggested. The repulsive force in space is due to the movement of the body in a magnetic field of another body. The formation of planetary rings depends on the mass and speed of the planet rotation.
