Build Your Own Magneto Charger
While a friend of mine had a magnet charger, I always felt a little uneasy about putting him to the trouble of ensuring that the battery that powered it was fully charged, and the fact he had to clear his work bench to make room to use it. Part of the satisfaction I gain from restoring engines arises from the turning of various bits of metal into a working piece of machinery, so I felt that to make a charger would be a new challenge, and that I would also learn something in the process. I knew little about electricity, apart from being able to change a plug, and knew even less about magnetism. Fortunately, I still met my old school physics teacher for a glass of beer most weeks, as we were both members of a local rifle club, more social members now with failing eyesight!
However, my hopes of an immediate flow of information just elicited the initial comment “yes, magnetism – a tricky subject,” and he started to talk about something else!
