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.
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.

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.
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.

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.
Why do magnet motors not work?
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.
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.
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.
Can you build your own electric motor?
However, on the more basic level almost anyone can build an electric motor using some cheap and commonly available tools. This simple electric motor uses electricity and magnetism to spin a wire coil that's supported by paper clips.

What happens when you wrap copper wire around a magnet?
A magnetic field pulls and pushes electrons in certain objects closer to them, making them move. Metals like copper have electrons that are easily moved from their orbits. If you move a magnet quickly through a coil of copper wire, the electrons will move – this produces electricity.

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.
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.
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.
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.
How much electricity can magnets generate?
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.

Can a static magnet generate electricity?
The magnet does not “run out” of magnetism; neither is it the source of the energy for the electricity generation process – it only makes it possible.
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.
Do magnets last forever?
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. There are a few things that may cause your magnet to lose its strength: HEAT.

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.
