Coil 400/500 Turns PS Conservation of Energy and Energy Transfer the expansion comes entirely fromThe 400 500 turn coil is center tapped so students can easily vary the configuration for investigations into the relationship between coil turns and voltage and the basics of Faradays Laws of Electromagnetic Induction. The coil can be wired using standard banana plugs for 400, 500, or 900 turns.
