This is the simple magnet charger I made last week. It is designed to charge individual magnets removed from the flywheel ... or still attached to the flywheel as illustrated here. To charge the other pole you simply turn the block around so that the other end of the iron core touches the magnet.
For those who didn't see the way this is used for individual magnets off the flywheel ... here it is below:
Mark, You don't need to physically reverse the orientation of the coil to reverse the magnetic polarity. you can simply reverse the Positive and Negative connections to the coil to reverse the magnetic polarity.
Like! Very compact and neat.
Hey Mike, Yeah I know I can reverse the connections but I have marked the fixture with North and South and for my dyslexic mind it's actually easier for me to keep track. Pivoting the fixture with one clamp on actually takes less time than removing the clamps anyway.
Noted; whatever works best for your setup. Good to have options. Good luck with magnet recharging. Glad you continued use of the solid wire re-charging coil and were successful in achieving the desired results without costly and unnecessary re-work using stranded wire.
What voltage are you using to snap these with?
