In this manner, there is no advantage to having the magnets work for us. Scientists and inventors alike have attempted to use permanent magnets alone to drive a motor. … A permanent magnet motor would not produce energy and would not be a perpetual motion machine.
Is free energy possible with magnets?
Because magnets do not contain energy — but they can help control it… … About 99% of the power generated from fossil fuels, nuclear and hydroelectric energy, and wind comes from systems that use magnetism in the conversion process.”22 мая 2012 г.
Is perpetual motion possible with magnets?
Magnetic perpetual machines can never work because magnets eventually wear out. This isn’t the reason they don’t work. Magnets can lose their magnetism in several ways; Heat them to very high temperatures.
Can magnets spin forever?
Anything can rotate infinitely, if there is no friction. Rotating an object with constant velocity uses no energy to maintain. With friction it will loose energy and eventually stop. … Now if you add a changing magnetic field, you can make it continuously rotate or even accelerate, but this requires energy to maintain.
How long will a magnet light last?
So how long should my permanent magnet last? Your permanent magnet should lose no more than 1% of its magnetic strength over a period of 100 years provided it is specified and cared for properly.
Is a permanent magnet motor possible?
Whatever the source may be, it is intrinsic and abundant. The notion of a motor driven by permanent magnets alone is therefore feasible and cannot be dismissed as defying conservation of energy. A permanent magnet motor would not produce energy and would not be a perpetual motion machine.
Is free electricity possible?
Free energy machines do not work. No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal. The law of mass-energy conservation states that mass-energy can never be created or destroyed.
What is the closest thing to a perpetual motion machine?

Why Perpetual motion is impossible?
A perpetual motion machine of the first kind produces work without the input of energy. It thus violates the first law of thermodynamics: the law of conservation of energy. … This conversion of heat into useful work, without any side effect, is impossible, according to the second law of thermodynamics.
Do magnets work in space?
Magnets can be used in space. … Magnets don’t need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves. One class of magnets, called electromagnets, does need electricity to work.
Do magnets eventually stop working?
No “permanent magnet” is completely permanent. Heat, sharp impacts, stray magnetic fields, and age all conspire to rob a magnet of its field.
Where do magnets get their energy?
Magnets are different to other objects. In magnets, the electrons in atoms at one end all spin in one direction, and those in atoms at the other end all spin the opposite way. This creates a force of energy around the magnet, called a magnetic field.
How do you increase the power of a magnet?
Take the magnet which has lost its power and stroke it with the stronger magnet. Linear strokes in a single direction will realign the electrons within the magnet, which will help its strength to increase. Stroke the magnet for around 15 minutes, and check to see if the strength has returned.
What happens when you wrap copper wire around a magnet?
By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak.
Do stronger magnets produce more electricity?
1 Answer. Yes, double the Gauss will double the output voltage, but only if the shape of the magnet remains the same. [SAFETY WARNING: for little kids, neodymium magnets wider than 15mm are a finger-pinch hazard. As a result, many DIY hobby projects avoid using neodymium magnets.]
Why do magnets lose their magnetism when dropped?
Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment. … The reason that would be hard to bump a piece of iron and make it magnetic is because of the way vibrations propagate in the material.
