Is it possible to make a magnetic motor?
There have been many attempts to produce a motor that relies solely on permanent magnets to generate magnetic fields for both the stator and the rotor. And while this discovery could lead to the commercial creation of a permanent magnet motor, it hasn't yet.
How do you make a magnetic motor?

The TKOR How To …YouTubeStart of suggested clipEnd of suggested clipYou'll want to touch the bent portion of your wire to the top of your battery. Next we want to bendMoreYou'll want to touch the bent portion of your wire to the top of your battery. Next we want to bend the two ends of our wire. So that they will run directly across the middle of the magnets.
Why are magnetic motors not used?
Practical implementations fail because there is no substantial energy in magnets that could be employed for propulsion or to compensate for energy losses. The force between permanent magnets is conservative as the magnetic field follows a potential, so that there is no work done over a closed cycle.
Is free energy possible with magnets?
Magnets don't contain free energy. They contain internal energy. It can be removed as the magnetism is lost. With the magnetic field there is an electric field vector circling the magnet, but eddy currents waste the electric potential.
Is a permanent magnet motor AC or DC?
A permanent magnet (PM) motor is an ac motor that uses magnets imbedded into or attached to the surface of the motor's rotor.
Can a magnet spin forever?
As the energy in magnets lasts for many years, the wheel is able to rotate and keep on spinning without the need to ever stop, thus the motion of the spinning wheel creates power for many years.
Can magnets spin forever?
As the energy in magnets lasts for many years, the wheel is able to rotate and keep on spinning without the need to ever stop, thus the motion of the spinning wheel creates power for many years.
How long will a permanent magnet motor 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.
Can you make magnets spin forever?
Anything can rotate infinitely, if there is no friction. Rotating an object with constant velocity uses no energy to maintain.
Why dont we use magnetic generators?
The amount of current a generator produces, depends mostly on at least three things: 1) how many loops of wire in the coil, 2) how fast the coil is spun and 3) how strong the magnetic field is. Earth's magnetic field is very weak, so you would get very little current from your generator.
Do Tesla motors use permanent magnets?
Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor.
How much voltage can a magnet produce?
The results of the tests showed that in no-load conditions, a permanent magnet generator was able to generate a voltage of 69.5 – 223.7 V and a frequency of 33.5 – 50.9 Hz when rotated at speeds of 2000 – 3000 rpm.
Do spinning magnets create electricity?
Spinning a coil of wire in a strong magnetic field We do this by spinning a coil (containing many loops of wire) quickly in a strong magnetic field. During each turn of the coil, electrons get a kick from the magnetic field, moving them along. This creates electrical current.
Do neodymium magnets last forever?
Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions.
Why don’t we use magnets for power?
Magnets don't create energy. They CAN convert it from electric energy to mechanical, and vice versa.
Why permanent magnets are not used in generators?
Now a days large generators are connected to grid. once it connected with grid, generator will produce reactive power and consume reactive power according to the Grid voltage level. with this condition we need to control our excitation voltage, which is not possible with permanent magnet.
How much power can a magnetic generator produce?
The results of the tests showed that in no-load conditions, a permanent magnet generator was able to generate a voltage of 69.5 – 223.7 V and a frequency of 33.5 – 50.9 Hz when rotated at speeds of 2000 – 3000 rpm.
Are permanent magnet motors more efficient?
Why only convert the front motors? Induction motors still produce high power due to their excellent control of magnetic fields. However, at low power, speed control of permanent magnet synchronous motors is more efficient.
Does Tesla use neodymium?
With a market capitalization of almost $1 trillion, Tesla is one of the most valuable automobile manufacturers globally. It uses lithium – battery – and boron – neodymium magnets – to deliver alternative energy sources and boron to provide a lighter, more muscular frame.
Can a permanent magnet motor generate electricity?
The study reveals that permanent magnet motors with rated 5.5 kW in elevators which is working by transferring mechanical energy into electricity when the motor is rotating without power therefore the motor is capable of producing electrical energy back into the grid system.
Do stronger magnets make more electricity?
Increasing the strength of the magnet will produce a stronger magnetic force on the wire and therefore more voltage (and therefore current). But that is not always easy. A bigger magnet helps but you can also make better magnets.
Are thicker magnets stronger?
As well as the material, geometry also has an effect on a magnet's Gauss value, for example, if you have two different sized magnets made from the same material with the same surface Gauss, the larger magnet will always be stronger.
Can you power a lightbulb with a magnet?
Turning the crank rotates a coil inside of the large U-shaped magnets. This creates a constantly changing flux (a flux in flux?), which by Lenz's Law induces a current within the coil. This induced current can be used to power the light bulb.
Can magnets rotate infinitely?
Anything can rotate infinitely, if there is no friction. Rotating an object with constant velocity uses no energy to maintain.
How much neodymium is left in the world?
eight million tonnes World reserves of neodymium are estimated at eight million tonnes.
Who has most rare earth minerals?
China China's dominance in world's rare earths China dominates the rare earths market globally. About 35% of rare earth global reserves are in China, the most in the world, according to the United States Geological Survey.
Can magnets spin a wheel?

Does doubling a magnet make it stronger?
Using two magnets together would be the same as having one magnet of their combined size. For example, if you stacked two 10mm diameter x 2mm thick magnets on top of each other you would have effectively created a 10mm diameter x 4mm thick magnet, essentially doubling the magnets strength and pull.
Does stacking magnets make them more powerful?
As you increase the height (or stack more magnets), each new bit of magnet material you add is farther away from the steel you're trying to attract to. Since it's far away, it doesn't add as much strength.
Can 2 magnets create electricity?
Can you make electricity from magnets? Yep, just as we can make magnets from electricity, we can also use magnets to make electricity. Here's how it works: A magnetic field pulls and pushes electrons in certain objects closer to them, making them move.
