Free energy from a permanent magnet and a wire wound around a magnet is positioned on the Internet as a kind of free energy. One, in the majority of cases, such an installation is not able to transfer the magnetic field energy of the magnet to the load, that is, to the consumer. Since, as it has long been known, in order to induce an electromotive force in a nearby conductor, this conductor must constantly intersect the magnetic field of a permanent magnet at some speed. A complete analogy will occur if the conductor is left stationary, and a magnet is also moved with a constant speed near it. But if both the conductor and the permanent magnet remain motionless, then the alternating electromotive force of the EMF will not induce in the conductor and no electric current will flow in it. So, the free energy of a permanent magnet in this context is of no practical use.
But you could observe how the light bulb connected to the wires wound around the ring magnet glows. And all this is in a fixed state. The fact is that under the table of such a free energy getter there is a powerful AC electromagnet, for example, a Tesla transformer. Accordingly, around it is formed an alternating magnetic field, which induces a variable EMF in a conductor wound on a magnet. Under the action of a variable EMF when the circuit is closed by means of a bulb, alternating current flows in this conductor, which actually illuminates the lamp. Free energy is here unfortunately or fortunately nothing to do with.
