Hi! I want to share my next idea.
I hope this post will add some fun during these holidays.

Idea : Flat rotor available . On the permanent magnet side, the rotor has a magnetic field shield.
On the coil side, the rotor has a ferromagnetic material .
When the rotor gets closer it reduces the magnetic field in the coil.
If the electric circuit of the coil is closed, then changes in the magnetic field lead to the appearance of an electric current in the coil and,
as a consequence, to its own magnetic field (Lenz). In this case, the magnetic field of the coil (Lenz) accelerates the rotor.
When the rotor begins to move away from the coil and magnet, the coil's electrical circuit must be open.
Opening the coil's electrical circuit interrupts the electrical current and causes the coil's magnetic field to disappear (Lenz)
Now the retreating rotor does not experience any opposition from the coil.
Now let's look at the big picture.
The permanent magnet acts on the rotor with the same force both when approaching and when moving away.
The coil accelerates the rotor only when it approaches.
When moving away from the coil, the rotor experiences no coil resistance.
With the addition of all forces, a pronounced acceleration of the rotor is noticeable.
We now have a free energy generator with a self-rotating motor.
Moreover, the more electrical energy this device generates, the faster the rotor rotates.
Merry Christmas
