The effect of finite electron mass on the formation and sustainment of a field reversed configuration (FRC) by rotating magnetic fields (RMF) is studied. The importance of inertial effects is measured by the ratio between the RMF frequency ({omega}) and the electron-ion collision frequency ({nu}). In the limit where this ratio is very small ({omega}/{nu}{yields}0), previous results corresponding to massless electrons are recovered. When {omega}/{nu} increases there are significant changes in the value of the minimum external rotating field needed to sustain the FRC and the time required to reach a steady state. Since {nu} decreases with increasing temperature and decreasing density, these effects are expected to become more important as fusion relevant temperatures are approached.
