How to Make a Simple Electric Generator(2)
Steps
3.Build a "U" shaped frame to support your "rotor", ie, the permanent bar magnet mounted on a steel shaft. by
a.Cut the 1X4 lumber into pieces, 2, at 6 inch lenths, one at 12 inches in lenght.
b.Nail or screw the two 6 inch boards to the 12 inch board at a perpendicular angle to the 12 inch board, which is the base for the rotor frame.
4.Drill two 1/4 inch holes in the two uprights of your frame, aligning them so that the 1/4 inch rod, (the rotor shaft) will go through both without binding.
5.Drill a 1/4 inch hole through the center of your bar magnet, on the flat, or widest side. Be careful to measure the center both in length and width, and drill perpendicularly, so that when the shaft goes through, the magnet will be "square" to the shaft.
6.Slide the metal shaft through one side of the support frame, slide the magnet onto the shaft.
