DELUXE CURRENT BALANCE KIT ,Each

Details

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, while the other half has an adjustable counterweight that can carry light additional masses. When current is supplied to the balance and solenoid from an external power supply, the balance deflects. By adding light masses until balance is restored, the force on the conductor can be measured.
