Electronic Devices,lectric field, and we shall see that this necessitates positive as well as negative carriers and therefore does not apply when the carriers are electrons only. In the latter the cathode temperature is raised. This causes the ions of the metal to oscillate and collisions between ions and electrons at

The Magnetic Fields Produced by Electric Currents,sted in 1820. He was demonstrating what he believed to be the non-connection between electricity and magnetism. On arranging a current-carrying wire parallel to a compass needle he was surprised to find that the needle was deflected. On reversing the current the defection was reversed.
