Dear all, I am trying to design a modulation coil that can produce 1 G magnetic field at the center of solenoid along its axis. The coil should be of radius 3.5mm and length 10mm. I am getting confusion for the number of turns.So I am looking for some suggestions for that. Thanks Sincerely, Indra
Not my area of expertise, but it appears that inductance is proportional to ampere-turns, so you must think about how much current you have available, and can easily handle. Then you can get an idea of wire size, wind the coil based on that, and then use the gauss meter as you raise the current.
The approximate formula for inductance of a single layer air core coil is:
L = ((N*A)^2)/(9A+10B) where A is radius and B is length (I think based on inches)
