A coiled tubular electric battery is a conductor through its electrolyte and it may coincide with an electromagnet and a wire coil. The electromagnet is powered by the battery and caused to pulsate whereby its fluctuating magnet is equivalent to relative motion between the coils and the magnet. Current is increased by ampere turns in the wire induction coil while voltage is increased by series connection of the battery cells.
