ID Code: K2-04
Purpose: Shows that the induced current is proportional to the number of turns in the secondary coil
Description: Three coils are connected in series with a projection galvenometer on an overhead projector. A bar magnet is thrust through one of the coils, inducing current in the coil which is shown on the meter. Three coils are included on the device: 20, 40, and 80 turns; the bigger the coil the greater the induced current.
