The so-called perpetual motion machine is an imaginary machine that can continuously move and do work without external energy input or only one heat source. But obviously, it is impossible to exist in reality because it violates the law of conservation of energy.
Extended data
Magnetic perpetual motion machine is another name for magnetic motive. Its working principle is the mechanical movement caused by the principle that the same names repel each other and different names attract each other between the north (N) pole and the south (S) pole of a permanent magnet. But magnetic motive is also based on the theory of conservation of energy, and has not divorced from the laws of physics. This type of perpetual motion machine is not a machine that can move forever. The name is just a relative term.
Permanent magnetic energy can do work, of course, it can be a power machine, but the magnetic perpetual motion machine, that is, magnetic motive, is not a real perpetual motion machine. Because only the machine that creates energy is a perpetual motion machine, and the machine that converts energy is not a perpetual motion machine.
Brief introduction of perpetual motion machine
Perpetual machine is an imaginary machine that can continuously move and do work without external input energy or only one heat source. Historically, people have been keen to develop various types of perpetual motion machines, including scientists such as Leonardo da Vinci and Joule. In addition, there are some swindlers and enthusiasts who want to be famous and make money with perpetual motion machines.
After the establishment of the thermodynamic system, people proved that the perpetual motion machine violated the basic principles of thermodynamics through strict logic. Since then, there have been few researchers on perpetual motion machines. However, from one side, we can also think that human enthusiasm for perpetual motion machine and various practices of manufacturing perpetual motion machine have promoted the establishment of thermal system and the progress of mechanical manufacturing technology.
