The trajectories of individual electrons are studied numerically in a 3D, prolate, FRC equilibrium magnetic geometry with added small-amplitude, slowly rotating, odd-parity magnetic fields (RMF<sub>o</sub>s). RMF<sub>o</sub>s cause electron heating by toroidal acceleration near the O-point line and by field-parallel acceleration away from it, both followed by scattering from magnetic-field inhomogeneities. Electrons accelerated along the O-point line move antiparallel to the FRC's current and attain average toroidal angular speeds near that of the RMF<sub>o</sub>, independent of the sense of RMF<sub>o</sub> rotation. A conserved transformed Hamiltonian, dependent on electron energy and RMF<sub>o</sub> sense, controls electron flux-surface coordinate.
