Description:Two square 1,000-turn coils are mounted one inside the other. The larger exterior primary coil is connected to a 6V battery and keyswitch; the interior secondary coil, to a projection galvanometer.
Closing or opening the switch starts or stops current in the primary coil, inducing a voltage in the secondary which is seen by the galvanometer.
Note that the primary coil is also used for demonstration K2-27: Mutual Induction - M21=M12; be prepared to swap components if using both demonstrations.
Loc codes:K2, K4
