Hello guys, I had just received my assignment from my lecturer, the objective is to design and built a 100μA range tangent galvanometer . How to do it ??? Thanks for help :grin:
 

With G00gle you can easily find how to do this: see here a construction guidance for a 10" (25cm) Ø coil with 8 turns (windings) for a 45° deflection at 500mA. Extrapolated this would mean you'd need 5000*8 = 40000 turns :-( for 100µA !

So it would probably be wise to use a much smaller coil & compass!
 
40000 turns ... sounds crazy :shock:
Anyway , really appreciate for your help man, thanks :grin:
