This kit includes an air core solenoid and a current balance for demonstrating and measuring the small force experienced by a conductor carrying an electric current in a magnetic field. To run the experiment, one half of the current balance is placed inside the solenoid. The other half has an adjustable counterweight and can carry light additional masses. When current is supplied to the balance and solenoid from an external power supply, the balance deflects. Adding light masses until balance is restored allows the force on the conductor to be measured.

Air core solenoid includes a clear acrylic former and large diameter to easily fit the current balance. Five tappings give easy access to windings of 100, 200, 300, 400 and 500 turns by simply moving one plug between the five red binding posts. The coil has a total resistance of 20 Ω or 4 Ω per 100 windings and can carry up to 1.5 A of current in a single 100-turn segment, allowing a 6 VDC power source to be used (and up to 12 V for the full 500 turns).

Ordering information: Includes activity guide. Required but not include is a power supply capable for two Amps.
