Just out of curiosity, are you using the same formula as that for a solenoid? Are you using relative permeability - which I think might be your figure, the Permeability of Air, divided by the permeability of free space, 4*pi * 10^-7 T*m/A? I like to use * instead of x because I don't always know when x is referring to a cross product. I just wanted to make sure that by writing T*m/A I meant units - not variables.Hi,
I am trying to calculate the magnetic field strength of an air core coil.
I have found the Permeabillity of Air is 1.256 x 10^-6,
My question is, for the 10^-6 is this just .00000010
so the Permeabillity of Air is 1.256 x .00000010
I am not sure, is this correct.
