  • How To Build A Magnet Charger (Guide)

    Be patient, these are LARGE images; they will sometimes take a moment to load but WORTH IT if you want to build this.

    Ah yes, the old magneto charger article. That's a nice clean copy too.

      Has anyone on the forum ever built it?

        Is anyone here educated enough to tell me how this can be built as a plug-in? Even if it requires more parts...it would be nice to not have to worry about the battery and whether or not it is charged up. How strong (amps rating) of a power supply would one need?

          Someone here (Can't remember who right now ) built Gingerys magnetizer ,& had some problems with it & that's why I never tried building it

              Electric Davyboy built one I think.
              Robert, think about it, a lead acid car battery can put out 700-800 "Cold Cranking Amps" as the ads say. You can't get that much juice out of a wall outlet without some form of storage. You can either go with capacitor banks or with a really big, iron cored transformer. WHat's so hard about using a trickle charger and keeping the thing plugged in?

                  Looks like someone took a page from your book LOL

                    It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

                      I love the burn marks on the wall behind the magnetizer!

                        Electromagnets are all about amp-turns. This thing runs off 12V at 40A, you can get exactly the same result with 120V, 4A. Just use 10x as many turns, of magnet wire with 1/10 the cross-sectional area.

                        Obviously you have to use DC. You can plug it into the wall using a bridge rectifier. Put the switch on the AC side of the rectifier, and when you turn it off the rectifier will act as a flywheel diode to discharge the magnetic energy safely. Put the switch on the DC side if you want it to die instantly in a huge flaming arc.

                        Large neo magnets may be a better solution nowadays if you don't mind handling them.

                            With the PE wire ,the magnet wont sound so harsh....

                              I built Gingery's magnetizer myself a few years ago, but IMO it didn't really have quite enough oompf to get magnets completely charged even at 10A measured at 120VAC input. I was thinking about some kind of power amp for it to raise the energy going to the coils to do a better job. I used modern 150C rated coil wire, and a cap bank made of 500VDC caps (mil surplus) too.
