We predict the appearance of a uniform magnetization in strained three-dimensional p-doped semiconductors with inversion symmetry breaking subject to an external electric field. We compute the magnetization response to the electric field as a function of the direction and magnitude of the applied strain. This effect could be used to manipulate the collective magnetic moment of hole mediated ferromagnetism of magnetically doped semiconductors.
