Phys. Rev. Lett. 69, 3593–3597 (1992)Origin of the geometric forces accompanying Berry’s geometric potentialsReceived 12 May 1992; published in the issue dated 21 December 1992 We consider the dynamics of a particle carrying a magnetic moment in a strong magnetic field whose direction varies slowly in space. In particular, we discuss the geometric Lorentz-type and electric-type forces that were discovered in studies of Berry’s phase. We show that the Lorentz-type force felt by the particle is caused by a small misalignment of the magnetic moment with respect to the magnetic field while the electric-type force is the time average of a strong oscillatory force induced by the precession of the magnetic moment. © 1992 The American Physical Society URL:
