Corrector Magnet

Corrector magnets. The horizontal corrector magnets are of square cross-section and are carried on slides on a graduated brass tube 14.3" (67cm) long. The tube can be slewed and a scale at top shows the angle of slew. The vertical magnets are inside the tube and the other end of the chain is attached to a slider on a graduated rod.
