Clock spring balance
A sensitive balance for use among 0-1 g or 1-10 g is readily made using a piece of clock spring and a block of wood or cotton reel.
Fasten the wooden block or cotton reel down to a convenient base. Fix a piece of watch spring about U) cm long to it and make a cardboard or paper conical pan. Fix the pan to the spring near the free end using sealing wax or cements suggested in Chapter XVIII. Use the free end as a pointer, and a postcard as a scale, and calibrate it by putting weights in the pan. The sensitivity depends on the spring used, but the scale is a reasonably open one.
These materials are used for permanent magnet manufacturing because of their low cost and their low weight. It consists of low iron oxide in combination with either barium carbonat
