A classical analytical formula for demagnetization tensor of two uniformly magnetized parallel to each other blocks (Newell et al.(1993)Newell, Williams, and Dunlop) has been generalized for the case when the bodies are oriented arbitrary with respect to each other. Account of arbitrary orientation of the blocks makes computations much more complex and tedious, nevertheless the final formula can be expressed as a sum of several repeated expressions with small differences the similar manner as it is done for parallel blocks’ case. The result can be applied for spin ice systems.
