For Schrödinger operators, the inclusion of a magnetic field raises the energy. This is the consequence of a basic inequality due to Kato. A variation on this question—namely, monotonicity of the ground state energy as a function of the parameter B—is of central importance in the theory of superconductivity and is discussed in Section 2.3 here and repeatedly in the book.
