Although, realistically we will usually burn a part of the Electricity restively because of wire resistance on your own, whilst the magnetic Main will insert its possess impedance on best, this although cuts down as the inductor/magnet builds its magnetic field. In other words, the slower we alternate the polarity, the greater resistive losses we could have.
