The deluxe Current Balance set contains the solenoid, current balance and fractional weights. All you need to provide is a power supply. (Up to 12 V and 1.5 A)

Solenoid:
A convenient, well-made solenoid for investigating the magnetic field of a coil and for the current balance experiment. The clear acrylic former and the large diameter (90mm) allow items placed inside the coil to be easily seen.

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 carryup to 1.5A of current in a single 100-turn segment, allowing a 6VDC power source to be used (and up to 12V for the full 500 turns).

Current Balance:
The classic method for demonstrating and measuring the small force experienced by a conductor carrying an electric current in a magnetic field. One half of the balance is placed inside a solenoid. The other half has an adjustable counterweight and can carry light additional masses. When current is supplied to the balance and the 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.
