Sorry Bob Edited: I am missing something, u0 = 4 pi x 10-7 Henrys per meter, = Permeability of Air------Correct? Say L Inductance is 300uH or 400uH instead of 200uH how does L fit into the equation?

Thanks Bob S, The coil Radius is 150mm--300mm Diameter, i am very interested to know how the diameter affects the field strength. I see you mention the B field "inside" the coil, is there a way to calculate the strength of the B pulse at distance away from the coil, say 25mm 50mm 75mm etc...

I'm new to the forum, so hello! How can i calculate the magnetic field strength of the pulse of an air core coil, the number of turns is 20 & the height of the coil is 20mm, not single or multi layered just random wound. The pulse is 10V & 1Amp, the Inductance is 200uH. Not sure how to go...
