Product Code: PHY-326
6" dia plastic bobbin with 3 windings of 2, 50 and 500 turns. The magnetometer is supported on a brass tube fitted on an ebonite plate which is free to revolve in the base of the instrument. The magnetometer and the ring can both be rotated independently of the base of the instrument. The magnetometer and ring can both be rotated independently of the base which is with levelling screws. Compass box consists of a bakelite case with metal 100 mm dia dial graduated in degrees and anti parallax mirror. Cobalt steel magnet and aluminium pointer are mounted on special synthetic sapphire. The needle moves on special pivot. The above combination makes the needle practically frictionless.
