A water management project requires a "wet coil" (coil will be submerged in aqueous media) designed to generate a steady-state electromagnetic field of adjustable magnetic magnetic flux density at the center. The coil will be helical with a hollow core (wound on a nylon perforated cylinder used as former). The inner diameter of the coil needs to be between 6 and 12 centimeters, say 8 cm to put a number to it.
I would like to understand how to compute the number of turns needed, and the current that must be driven through the coil, to generate a specific magnetic flux density.
In this context the required range is from 0.1 Tesla to 1 Tesla, but I would rather understand the method than the result. Also, if there are any suggested commercial resources / products to look at, for both coils and drivers, pointers would be very helpful.
My background is oriented more towards banal analog and digital electronics and software, than electromagnetic phenomena or applied physics. Though I did learn basic electricity and magnetism 2 decades ago, that's all very rusty. Hence, I apologize if my question leaves too many gaps, please let me know and I will amend the question accordingly.
