Current Balance (BIL Coil)

This current balance apparatus (BIL coil) consists of a printed circuit board coil mounted on a support handle. The board has 2 coils one with 5 turns and one with 10 turns, rated at 2 A. The apparatus can be used to measure the force on current carrying conductor in magnetic field. permanent magnet should be placed on the pan of digital balance (a yoke with 2 ceramic magnets will work) and the BIL coil mounted in vertical plane between the magnets. When connected to low voltage power supply and ammeter, the balance will be deflected and the new reading can be taken. The force on current carrying conductor and field strength can then be calculated.
