Abstract: An electric generator includes a magnetic flux generating unit that generates a magnetic flux, a rotation unit that rotates about a rotation axis, and an induction coil unit including a winding. The magnetic flux generating unit, the rotation unit, and the induction coil unit are arranged along the rotation axis. The rotation unit is disposed between the magnetic flux generating unit and the induction coil unit. The rotation unit includes a magnetic flux changing part. The magnetic flux changing part passes across a space through which the magnetic flux linked to the winding passes, by a rotation of the rotation unit. A density of the magnetic flux linked to the winding is changed by the magnetic flux changing part passing across the space. An electromotive force is induced in the induction coil unit in accordance with the change in the density of the magnetic flux linked to the winding.
