I am trying to build a home generator off of a VW bug generator and a exercise bike. Ride the bike---see the light turn on, for a sciene project for kids. Does anyone know if the generator of VW bugs had "permanent magnets" or do I need to hook up a battery to the generator to develope a field current (energize the magnets). Any help would be great. Any other suggestions would help as well. I am at the trial and error part.

You generate electricity by moving coils of wire through a magnetic field. Both alternators and generators use an electromagnet to generate the manetic field, because you can control the output by varying that field. The energy required to make the field is much less than the output, so it is only slightly counter productive. The down side is if you have no electricity to get it started, it won't generate anything. |
