Current passes through the coil of a galvanometer, causing a magnetic field, similar to what happens in an electromagnet. The field pulls the coil towards a permanent magnet attached to the frame of the galvanometer. There is a spring attached to the coil which controls how far it can move, which depends on the current. The frame has to b aluminum or some other non-magnetic material so as not to screw up the intensity of the magnetic fields, which would mess up the accuracy of the galvanometer.
