il when circuit is made; (9.)db, the direction when the circuit is broken. Use a cell to determine the direction of current corresponding toeach deflection. 118 INDUCED CURRENTS. EXPERIMENT 56. THE DYNAMO. Method.—1. Connect the hand dynamo so that the fieldwindings are in series with a resistance… … Dynamo. When the observations are made the number of turns of thecrank should correspond to the ticks of the metronome. Findthe voltage for external resistances varying from .1 to 15ohms. 2. Connect the dynamo so that the field magnets willhave shunt windings, and proceed as with the series…
