Experiment 1. — After all the connections are made, and a current isestablished in the primary circuit, and the galvanoscope needle is broughtto zero, lower… … Fig. 438. is a movement of the needle, showing that a current must have passedthrough the secondary circuit. Let the primary coil rest within, thesecondary, until the needle comes to rest. After a few vibrations theneedle settles at zero, showing that the secondary current was a tem-porary one.…
