Body
Mick, first envision a North-South magnetic poles embedded in flywheel.
When the North-South magnets bridge the first two poles of the stator
(rotation) a forward going current is induced into iron core coil and at
same time charges up condenser to max. Important note here is that the
impedance of coil is LC matched to the value of the condenser. When
the North-South magnets move over to the middle and last poles, breaker
points open and at same time a reverse current is being induced into the
iron core coil with the reverse polarity, the condenser discharges
through coil windings to frame ground. With the condenser being charged
via the forward going current, 1st step, when it discharges into coil a
reverse current is being induced by moving magnets. In effect you have
opposing currents, opposite polarity, (BUCKING-OPPOSED) which cause a
miniature magnetic flux annihilation event and a MAGNETO-ELECTRIC, micro
EMP event. That is the reason the old magnetos had such a powerful spark
even when you turned them by hand at super low RPM. I worked on
thousands of them on my magneto test bench. Norm
