1. An electrical power generator, comprising:
- a first part having a first terminal end and a second terminal end, the first terminal end being configured to be anchored in an anchoring point, the second end being free such that the first part can perform an oscillating movement, the oscillating movement being a swaying movement of the first part relative to the anchoring point, the first part being configured to be located in a fluid and configured such that, when said fluid moves, vortices in the fluid are generated such that a lift force is generated on the first part, producing the oscillating movement of the first part relative to the anchoring point, wherein said oscillating movement has an amplitude that varies according to a velocity of said fluid;
a second part that surrounds, at least partially, said first part;
a system having at least one first magnet attached to the first part and at least one second magnet attached to the second part, the system configured to generate a magnetic field between the at least one first magnet and the at least one second magnet that produces a magnetic repulsion force between the first part and the second part, wherein the at least one first magnet is arranged at a distance from said at least one second magnet such that the distance varies with the oscillating movement, wherein the magnetic repulsion force generated by the at least one first magnet and the at least one second magnet, varies with the oscillating movement of the first part due to variation of the distance between the at least one first magnet and the at least one second magnet, such that an amplitude of the magnetic repulsion force increases when the amplitude of the oscillating movement of the first part increases; and
a subsystem of magnets configured to induce electrical current in at least one coil, the generator being configured such that the oscillating movement of the first part produces a relative displacement between the subsystem of magnets and the at least one coil, such that an electromotive force is generated in said at least one coil.

Abstract
An electrical power generator includes a first part configured to be located in a fluid such that, when the fluid moves, it generates vortices in the fluid so that a lift force is generated on the first part, which produces an oscillating movement of the first part, which has an amplitude. The natural oscillation frequency of the first part may be adjusted to wind speed by way of magnets, which repel each other. Magnets may also be used to generate electrical currents in coils. The first part can have a diameter that increases with distance above the base of the generator.
