Can small magnets actually create a perpetual motion generator?

Introduction Can a small magnet really create a perpetual motion generator? Perpetual motion is a concept that violates objective scientific laws and cannot be created. A perpetual motion machine is what we call a machine that does not require external input.

Can small magnets actually create a perpetual motion generator?

No. Perpetual motion is a concept that violates objective scientific laws and cannot be created.

A perpetual motion machine is what we call a machine that can move and work continuously without external input of power, energy or a single heat source.

A machine that can work forever without consuming energy violates the law of conservation of energy, which is why it is called the "first type of perpetual motion machine." A machine that continuously absorbs heat from sea water or air in nature and continuously converts it into mechanical energy without temperature difference. It violates the second law of thermodynamics, which is why it is called "the second type of perpetual motion machine."

These two types of perpetual motion machines are concepts that violate current objective scientific laws and cannot be created.

Detailed information:

The origin of the perpetual motion machine

Perpetual motion The idea of ​​motivation was born in India Around 1200 AD, this idea spread from India to the Islamic world, and from here to the West.

In Europe, the most famous perpetual motion machine design was proposed by a Frenchman named Hennecaut in the 13th century. There is a rotating shaft in the center of the wheel, and 12 movable short rods are installed on the edge of the wheel. An iron ball is installed at one end of each short rod.

The system designer estimates that the ball on the right is further from the axis than the ball on the left. Therefore, the rotational torque generated by the ball on the right is greater than the rotational torque generated. by the ball on the left. In this way, the wheel will rotate endlessly in the direction indicated by the arrow and cause the machine to rotate.

This design wascopied by many people in different forms, but it never achieved non-stop rotation. After careful analysis, you will find that although the torque generated by each ball on the right is large, the number of balls is small, and the torque generated by each ball on the left is small, but the number of balls is large. Therefore, the wheel will not continue to rotate and do external work, but will only swing a few times and then stop.
