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
