show that a direct currentis induced. Prom this we seethat when the primary coil,hearing a current, is broughtnear or thrust into the sec-ondary coil, an inverse cur-rent is induced in the latter;that when the coils are sep-arated, a direct current is induced in the secondary coil; that the… … Fig. 239. 338 INDtJCEi) ELECTRICITT, 463. Magneto-Electric Currents.— We havealready noticed that there is an intimate relation betweenelectric and magnetic action. We have seen that an elec-tric current may develop magnetism. Faraday found thatelectricity may be developed by magnets; the results…
