aR1 is the inner radius of the coil. The average radius is R1+H/2, the outer radius is R1+H. | |||||||||
bW is the width of the coil, i.e., the cross section of the windings. | |||||||||
cH is the height of the coil windings. | |||||||||
dR denotes the Ohmic resistance at DC. In case of the measurement coils, it is the series resistance of both coils. | |||||||||
eL denotes the inductance, measured with an inductance meter at 1 kHz. |
