- In sensitive galvanometer, the coil is supported by a flat ribbon suspension which also carries current to the coil
- The other current connection in a sensitive galvanometer is a coiled wire, this is called the lower suspension and has a negligible torque effect
- This type of galvanometer must be levelled carefully so that the coil hangs straight and centrally without rubbing the poles or the soft iron cylinder
- Some portable galvanometers which do not require exact levelling have “taut suspensions” consisting of straight flat strips kept under tension for at both top and at the bottom
