Webwe adopt the system of natural unity were=c=1,and the terms of O(E2)and O(B2)are neglected,µis the magnetic dipole moment,d is the electric dipole moment,E is the electric field,andB is the magnetic field.In fact,the Hamiltonian consists two different physic effects,including Aharonov-Casher effect and He-McKellar-Wilkens effect.In which the ... WebIf you have a solenoid with a uniform time-varying magnetic field, then an electric field is induced by Faraday's law. It will be a circular field, and will make an electron at rest spiral. So the electron at rest is affected by a time-varying magnetic field, though indirectly--via an induced electric field.
