thanks for responding!
so does that mean I've got the right idea?

I can't find any where that says what this diode (1n4001) is for but am i right in guessing that when the power coil fires, its magnetic field induces a current in the trigger coil in the opposite direction to the current induced by the magnets and thus quickly turns off the transistor as soon as it opens which results in the sharp pulsing? ...
...and allows for multiple pulses per magnet.

if not how does the transistor turn on and off multiple times per passing magnet?
