On the other hand, an auxiliary magnet 500 is disposed around the cylinder 100 to form an attractive force or a repulsive force together with the permanent magnet 300.

As described above, the coil 200 is wound around the center portion of the cylinder 100. When the permanent magnet 300 vibrates up and down in the cylinder 100, the magnetic field is changed, A current flows through the second transistor 200. The electricity generated by the induction current may be used immediately or may be stored in a separate battery.

The permanent magnet 300 is disposed at an inner center portion of the cylinder 100, and electricity can be generated using an induction current generated according to the movement of the permanent magnet 300.

The supporting means 400 is provided on the upper and lower surfaces of the cylinder 100 so that the permanent magnets 300 are lifted at the central portion of the cylinder 100, Or repulsive force. That is, the permanent magnet 300 supports the permanent magnet 300 such that the permanent magnet 300 does not collide with both ends of the cylinder 100, but is positioned at the center of the cylinder 100.
