### Abstract

It is shown that chiral symmetry is spontaneously broken by a constant magnetic field in QED. The dynamical mass of fermions (energy gap in the fermion spectrum) is mdynC eB exp[-(π/α)1/2], where B is the magnetic field, the constant C is of order one, and α=e2/4π is the renormalized coupling constant. Possible applications of this effect are discussed.
