In thinking about the primary induction and secondary self induction
that you mention, Im wondering if there is a third component to the
Say the primary fires and the primary induction creates a voltage
profile on the secondary. Any voltage gradient from say one turn to
the next will start a traveling wave following the wire path. The
current from this traveling wave will result in self induction of the
1. Primary induction happens almost instantaneously across the entire
coil. Magnetic field travels at speed of light from primary to a
particular turn on the coil and in general the arrival of the field
will be a little different from one turn to another.
2. The traveling wave follows the wire path (one component to the
total poynting vector) and time taken to reach the top of the coil is
the time taken to propagate the wire path. For a 1000 turn coil
probably 1000 little traveling waves each starting from a different
turn of the coil if you get my meaning here. Maybe take the primary
induction profile as initial conditions on the wire path and start
propagating a forward and reverse wave (I got to think more about this).
3.The current flowing by the traveling waves creates a magnetic field
that propagates at the speed of light to all other turns in a direct
path instead of following the wire path.
The total voltage at any given instant would then seem to be the sum
of all three effects. Does this paradigm seem reasonable???
