    main thing is diode polarity being correct so things dont blow out. with DC electron flow (- to +) you might get a very slight difference in the electromagnetic coil's strength one way vs the other? I'd doubt it'd really be noticeable if there is an actual difference for that, it all being "light speed".

    great explanation ramegoom. some of that spike may also come from the solenoid return spring shoving the steel back out of the coil same moment power to the coil is cut? I've been tinkering with PMA wind power lately, coils and magnets basically making AC spikes.
