I'm working on an application where I need a simple DC coil that provides a particular magnetic field strength. I have to experiment to determine just how strong the field needs to be. So I have wound an arbitrary coil to experiment with. I will vary the voltage on it until I experimentally achieve the necessary field in my application.
Now when I know that this coil is producing the right field, how can I measure it? If I can get a measurment of the field intensity, I can wheel-and-deal mathematically with different voltages, wire gauges and dimensions of a coil so that I can design one to meet the field requirement.
Is there a simple way to do this without expensive equipment? I suppose I could take apart my arbitrary test coil and calculate what the field must have been, working backwards, but is there a more direct, emperical way? I want to be able to say, "My application requires ______ teslas".
