  The equations which determine the response of a spinning charged particle
moving in a uniform magnetic field to an incident gravitational wave are
derived in the linearized approximation to general relativity. We verify that
1) the components of the 4-momentum, 4-velocity and the components of the
spinning tensor, both electric and magnetic moments, exhibit resonances and 2)
the co-existence of the uniform magnetic field and the GW are responsible for
the resonances appearing in our equations. In the absence of the GW, the
magnetic field and the components of the spin tensor decouple and the magnetic
resonances disappear.
