I wanna power my house with a magnetic generator how strong of a magnet would I need
Depend how solutions you chose for these. You can use with good results this solutions:
1″ diam. x 1″ inch length neodymium magnets. I recommends not going bellow 7/8 inch diameter, but “it may still work with using smaller magnets”.
The spacing between the rotor magnets, from the leading edge of one to the trailing edge of the next, should be 1/2x the diameter of the magnet.
The length of the magnet is not critical, but the rotor and stator magnets need to be the same size. You can read this post:
