The velocity of the wave traveling on the turns of a coil is slightly
less than 300 million meters per second. Divide the number of meters of
wire in your coil by 300,000,000 and you get the number of seconds
required for the signal to get from one end to the other on the coil,
almost. Actual delay is slightly more because material surroundings slow
the wave a little more than a vacuum does. There is no magic
instantaneous transfer of energy from one turn to another within a coil.
If there were, Terman would have told us so.
