A wind power generator has a frame, an axle extending horizontally and rotatably mounted relative to the frame, a plurality of arms extending radially outwardly of the axle, a plurality of panels respectively connected to the plurality of arms, and an electrical generator positioned adjacent to the arms for producing electrical energy as the arms rotate relative to the frame. The electricity generator includes an annular housing, a coil positioned in the housing so as to define a pathway through an interior of the coil, and a magnet slidably received in the pathway so as to be movable through the coil as the axle rotates. The magnet is magnetically attracted to the arm.
