Mutual Inductance Program V3.1
Copyright (c) 1998, 1999, 2000 by Mark S. Rzeszotarski, Ph.D.
Solenoidal Primary Coil Geometry
Primary coil inside diameter (inches)= 4.400
Primary coil outside diameter (inches)= 4.400
Number of primary coil turns = 13.750
Last turn elevation in inches = 3.600
Wire diameter (inches)= .0800
Solenoidal Secondary Coil Geometry
Secondary coil diameter (inches)= 2.520
Secondary coil height (inches)= 16.400
Number of secondary coil turns = 2000.000
Secondary coil wire diameter (inches)= .0079
Calculational Results
Primary coil inductance in microhenries: Lp = 16.40
Secondary coil inductance in microhenries: Ls = 36410.54
Figure of Merit (square root of Ls/Lp) = 47.12
Primary coil wire length in feet = 15.82
Secondary coil wire length in feet = 1319.47
DC secondary resistance in ohms: 220.63
Secondary coil distributed capacitance in picofarads: 6.18
(Medhurst formula, assumes one end of secondary is grounded)
Mutual Inductance Results
Position is the secondary coil bottom wire position in inches
above the bottom wire of the primary coil.
A negative value means the bottom wire of the
secondary is below the bottom wire of the primary.
A positive value means that the bottom wire of the
secondary is above the bottom wire of the primary coil.
M = Mutual Inductance in microhenries
K = Coefficient of Coupling: K = M / square root ( Lp x Ls )
