Thanks Mike. The coils self supporting air core coils that are part of a Helmholtz design. I have some leeway on how the coil is designed. The only constraint is the ID needs to be 12" and I have a set # of turns. As such, I can modify the OD and the height of the coil to get my turns in...
For a round electromagnet, is there a general rule for the orientation that provides the maximum field along the axial centerline. Specifically, is there a ratio or relationship between the OD, ID and height of the coil that will maximize the field. Given a set # turns, the coil can be...
