of course magnet has free energy which is used. and magnet does not destroy its property of magnetism. did you saw any magnet lost it magnetism.
to make magnet energy is used one time and then megnet work forever.
but it is better than electric battery because battery will be discharge within 3 hours but magnet work forever.
but this is actually a perpetual machine on small scale. thick on lager scale you can generate electricity if you connect alternator with it.
our people just know how to make fun of others. not to help others and not willing to do research.
so, our fate is "Energy Crisis" , Load shedding, CNG Crisis, increasing fuel prices and terrorism. actualy our people are all mently sick and think somebody from sky will come and solve our problems.
my point is that it is working without providing continues supply of energy. so, it is perpetual machine. and laws of thermodynamics are broken forever.
This question really depends on what type of magnet you are talking about. Let us consider three types of magnets: Permanent magnets, electromagnets, and superconducting magnets.
The simplest of the three types, the permanent magnet, is made by magnetizing a special material using an external magnetic field. Once the external field is removed, the permanent magnet will retain some degree of magnetism and behave like a magnet for a long time. Metal alloys such as Neodymium-Iron-Boron (NIB) or Aluminum-Nickel-Cobalt (Alnico), are often magnetized as powders, resins, or bulk materials that are then formed into shapes you see on your refrigerator at home like horseshoes, donuts and circles.
Electromagnets are made by winding a coil of wire around a piece of material called the core. The core of many electromagnets is made of iron. When a voltage is applied across the wire, electric current will flow through the coil and create a magnetic field in the vicinity of the coiled wire. It is interesting to note that the strength of the magnet will change depending on the amount of electricity flowing through the coil (the more current that flows, the stronger the magnet), and the north and south poles of the magnet can be switched by reversing the direction of the current flow.
The third type of magnet to consider is a relatively new type that has developed over the last 30 to 40 years with the discovery of superconducting materials. Very special metal alloys (such as niobium-tin and niobium-titanium), when cooled to extremely cold temperatures (approximately -269C), will conduct electricity without any thermal resistance (loss of energy due to the dissipation of heat). These materials are called "superconductors". So, if there is a continuous loop of superconducting wire, cooled to the correct temperature, and charged with a certain amount of electric current, the current will flow indefinitely and generate a stable, persistent magnetic field. One popular application of superconducting magnets is seen in hospitals and clinics in a technique known as Magnetic Resonance Imaging, or MRI. These machines allow physicians to get very good photographs of soft tissue in the body and diagnose potential illnesses or injuries and treat them appropriately.
I have read in several places that superconducting materials are the closest phenomenon to perpetual motion known to science (constant flowing electrons within a circuit without resistance). The problem is that the energy required to cool the inducting material to its superconducting temperature would be far more than would be produced. However in space we have two advantages. One is the fact that it is a frictionless vacuum environment (you could rotate a disk with magnets on it without friction resistance) and the second is that parts of space are near absolute zero. Therefore theoretically you can have a free rotating dynamo inducting on a superconducting material at the surrounding ambient temperature. There would be no EMF feedback to slow the rotation of the disk. The freely moving magnets would induce a current on the superconducting coils without resistance. The energy could then be stored or used. And no energy would have been consumed in cooling the coils to superconducting temperatures. I must have missed something? Won’t this work?
