What is a magnetic motor and how does it work?
Have you heard of a magnetic motor? We explain its functionality and clear any doubts about its operation.
Since the dawn of humanity, access and use Energy sources They have shaped the course of every civilization that populates our planet. Although we believe that we are very different from our cave-dwelling ancestors, the truth is that we share the same struggle to take advantage of available energy resources to warm us, feed us, transport ourselves, and ultimately, thrive. We share.
He The energy challenge Our civilization has been diverted to the plane of climate. We want clean energy that does not emit greenhouse gases. However, if we analyze all the energy sources used by humans till date, we will see that we are always moving towards development. Technologies that have less impact on our environment. Either by destroying forests, or simply by saving costs.
However, we still have the same problems as our ancestors. Despite our advances in science, we could not Build a machine capable of generating unlimited and sustainable energy. Nuclear fusion energy seems to be the only way to achieve this goal. The best physicists of our age work there. On the other hand, there are such experiments Magnetic motorA machine that, on paper, would be capable of producing continuous energy.
What is a magnetic motor? where are you from
Can you make a motor using magnets? We are not talking about the well-known permanent magnet electric motors that many electric cars have, but about it Machines based on magnetism and attraction between magnets.
Magnetism has fascinated many scientists and inventors over the centuries. There is evidence that work on this type of generator began as early as 800 years ago. However, many have tried since the 19th century Develop a motor prototype using only magnets.
The best known today is the magnetic motor Parandev, a propellant that gained some notoriety after the figure of Michael Brady. It is possible to find many plans to replicate it on the Internet, although the scientific community has always shown complete rejection of its invention.
How does a magnetic motor work?
In this case the question should be more like “how does a magnetic motor work”. So far, the magnetic motor It has been developed only at a theoretical level. On YouTube you will find many videos of people who claim to have made both Parendev and many other earlier versions fully functional. But, for some unknown reason, they don’t want to show it to us.
In any case, the defenders of this technology claim that the magnetic motor works uncertainly Thanks to the placement of magnets so that the magnetic fields are in a constant state of distortion. They may require a small boost at start-up, but can then run without the need for external electrical or mechanical power.
A magnetic motor enters what we call “Perpetual Motion Engine”Something that is further along with science non-viable Contradicting many of the laws of thermodynamics, we will see a little later in this article.
What is the difference between a magnetic motor and a permanent magnet motor?
is great Difference between magnetic motor and permanent magnet motors. This second is widely used, especially in the electric car market.
He Operation of permanent magnet motor It’s simple. Magnets are fixed inside the motor, creating a constant magnetic field. When electricity passes through a coil of wire in a motor, it creates a electric field which interacts with the magnetic field of the magnet. This interaction produces a force that turns the motor rotor. Thus, electrical energy is converted into mechanical movement, driving the motor. It is a clean and very efficient propellant, although it is true that it is expensive to produce.
other side, A magnetic motor does not require an electrical current. Obviously, they should generate constant movement, just by playing with the magnet’s attraction and distortions.
Why are magnetic motors impractical?
The idea of being able to build a perpetual motion engine is undoubtedly appealing. However, the Laws of Physics They are quite spoilers in this sense. In practice, there is no evidence that there is a single functional prototype that uses this technology.
If you still have your doubts, here we give you the main reasons why this engine may not work:
First law of thermodynamics
The law of conservation of energy states that Energy can neither be created nor destroyed. It can only transform from one form to another.
Humanity has tried to violate this principle countless times, but physics has always gotten its way. Magnetic motor Denotes being able to produce perpetual motion without the use of external energy. That is, a magnetic motor can create energy from nothing.
Second law of thermodynamics
The theoretical approach of the magnetic motor also contradicts the second law of thermodynamics, which says that all systems move in this direction. entropy or disorder.
Basically, a magnetic motor is described as an ideal motor. It is capable of continuous movement, without heating and without loss of effectiveness due to friction. Therefore, we will talk about a closed system that operates forever without increasing its entropy. Another issue for physics.
Theory of Conservative Forces
Another reason why magnetic motors have gained so much popularity is the lack of knowledge about how magnetic forces—and forces in general—work. When we play with two magnets we feel attraction or repulsion force, but sometimes we cannot control it. They fully understand how it works.
A simple example to understand this principle of conservative forces is to think of a Ferris wheel. When you get to the cabin and go to the highest place, you will win potential energy. For this, electrical energy is required to move the attractor earlier. Then, when the wheel takes you back to the ground, that potential energy decreases and you gain kinetic energy. When the attraction stops and you return to the ground, you are the same as at the beginning. You have no more energy than when you started.
Magnets work the same way. They can push or pull other things, but in the end, this action is like someone riding a Ferris wheel: everything goes back to how it started. If you try to use a magnet to spin something continuously, you will find that, as in the carnival ride example, eventually Everything returns to its starting point without receiving anything extra.
Technical challenge
There are several designs of magnetic motors that can be reached Generate movement. For a while and after a good push, of course. To all this, we must add that the energy required to maintain the motion of the system will always be greater than the energy that can be produced. Hence some defenders of these engines claim that they are not very practical.
To all this, we must add, as we have said before Abrasion and air resistance. As much as it is said that these machines can work continuously, friction and air resistance will slow down the movement itself.
Lack of adoption at industrial level
Some defenders of the viability of magnetic motors maintain that they work perfectly, but are not manufactured because they are expensive to manufacture. The cost of the magnet. However, logic tells us that, if this engine were possible, someone would have managed to replicate one in the real world. It will not be for companies that have a lot of money in this world.
Other proponents of these engines argue that there are all kinds A conspiracy to bury this technology. In any case, after hundreds of years of experiments and a lot of literature on the subject, everything indicates that the magnetic motor is nothing more than a scam to attract the unsuspecting.
Magnetic motor. Is it cheating?
It all depends on how you look at it. The really beautiful thing about science is power Feel free to check, regardless of what the rest of the scientific community says. History is full of cases like Nikola Tesla or the Wright brothers, who were the subject of ridicule and doubt even though they were right. A more recent example would be James Dyson, who had to move heaven and earth to convince investors to finance his cyclonic vacuum cleaner. Other engineers believed that what was now the leading technology in its field was impractical.
All the research that has been done till date on magnetic motor is not in vain. After all, it is Important to humanity Learn what works and what doesn’t. However, magnetic motors have also been used as baits to make all sorts Scams. Therefore, we cannot guarantee that it is a fraud in itself; It is simply an impractical invention because it is inconsistent with the laws of physics.
What happened to Parendev engine?
Perendev Group’s magnetic motor did not have a happy ending. At the beginning of this century, Mike Brady secured financing from a good number of customers interested in his generator. Brady claimed to be able to build an electromechanical generator capable of producing 100 kW, so he soon had a million euros in his pockets.
Apparently, Parendev Group never delivered any device to any of its 41 clients. After several complaints, Brady was arrested in 2010. He was later charged with fraud and sentenced to 5 years and 9 months in prison.
We have reached the end. If you came this far because of a publication you saw on social networks about these types of motors, now you know that they are really practical. However, if you want to know a little more about the mechanics and the systems that work, we invite you to take a look at this article in which we explain how an electric car engine works.
