nikola tesla, of new york, n. y. coil for electro-magnets. SPECIFICATION forming part of Letters Patent No. 512,340, dated January 9, 1894. Application filed July 7...

Tesla’s patent “Coil for Electromagnets,” #512,340, states that the double series winding, whether as a flat spiral or conventional helix, eliminates self-induction and stores more energy than a single wound coil at resonance. Because such coils are not covered in textbooks, measurements were made on two similar coils of the same diameter ...

I have discovered that when so wound the effect of the small radius of curvature of the wire itself is overcome and the coil behaves as a conductor of large radius of curvature, corresponding to that of the drum.

In an electro-magnetic motor, the combination, with a coil adapted to be connected with a source of alternating currents, of field-magnets with laminations lying obliquely to the plane of the coil and a circular or disk armature with spiral or concentric laminations mounted between the field-magnets, both field and armature being under the ...

Nikola Tesla U.S. Patent 568,176 - Apparatus for Producing Electrical Currents of High Frequency and Potential

In the transmitting apparatus the coil A constitutes the high-tension secondary and the coil C the primary of much lower tension of a transformer. In the circuit of the primary C is included a suitable source of current G.

The improvement involves a novel form of transformer or induction-coil and a system for the transmission of electrical energy by means of the same in which the energy of the source is raised to a much higher potential for transmission over the line than has ever been practically employed heretofore, and the apparatus is constructed with ...
