WebWhen a bar magnet is moved through the coiling, the voltage detector measures the voltage in the circuit. Through his experiment, he discovered that there are certain factors that influence this voltage production. They are: Number of Coils: The induced voltage is directly proportional to the number of turns/coils of the wire.
