For families of magnetic self-adjoint operators on Zd whose symbols and magnetic fields depend continuously on a parameter ϵ, it is shown that the spectrum of these operators also varies continuously with respect to ϵ. The proof is based on an algebraic setting involving twisted crossed product C∗-algebras.
