YES A magneto indeed has a coil inside, how else you think it steps low voltage up to several thoudand volts necessary to arc current across a spark plug gap DUHHHHHHHHH
Its visible in the picture El Toro posted with its visible Wico lettering.....
It doesnt look like a typical tall thin can coil thats used on coil distributor ignitions, its more circular (actual windings) and has an iron core that goes through its center. It has a low voltage primary winding in the points circuit and a high voltage secondary winding whose output goes to the distributor rotor and eventaully via plug wires to the plugs.

If a mag is working correctly the spark should be a brigh visible blue and NOT any faint thin wimpy yellow spark.
Typical mag problems are burned or incorrect gapped points or a bad condensor or a bad coil.
