"Electricity is often called wonderful, beautiful; but it is so only in common with the other forces of nature. The beauty of electricity or of any other force is not that the power is mysterious, and unexpected, touching every sense at unawares in turn, but that it is under law, and that the taught intellect can even now govern it largely. The human mind is placed above, and not beneath it, and it is in such a point of view that the mental education afforded by science is rendered super-eminent in dignity, in practical application and utility; for by enabling the mind to apply the natural power through law, it conveys the gifts of God to man."  Michael Faraday

Induction Coils were the first type of electrical transformer, and when operated by an interrupted current from a battery produced violent shocks and long sparks in the air.  They became a practical power supply for X-Rays in the late 1800s and were pivotal tools in the early experimental days of radio and wireless telegraphy.
