The difficulties in developing a motor that runs entirely on permanent magnets are covered in the this article.
One particularly simple and easy DIY approach that sticks out is the Dietmar Hohl design.
The main obstacle is to create an adverse magnetic field, which is necessary for motor function.
The magnets must be configured to break their usual uniform field in order to do this.
The driving magnets of the Hohl motor are positioned at an angle to produce this asymmetry.
Building of Permanent Magnet Motors from nature:
According to the content, magnetic fields surrounding bar magnets are commonly taught to resemble specific patterns created by iron filings.
However, the magnetic field is altered by the iron filings, therefore this pattern is inaccurate.
The magnetic field really resembles a grid of football shapes surrounding the magnets ends.
“The Secret World of Magnets” is a book that more accurately illustrates this.
The majority of people are unaware of the true magnetic fields form, and internet searches frequently provide inaccurate images.
It is critical to understand that the magnets ends have a spinning magnetic field.
An uneven arrangement of magnets can provide a pushing force in one direction.
Magnets positioned at a 45 degree angle will be pushed in one direction by the corners.
However, it is not as simple as that since more magnetic lines are involved.
A gap may occasionally need to be left after a few magnets are placed.
This angled magnet technique was used to create a track by two individuals, Anthony and Andreas.
A neodymium magnet was employed to move down the track, and several ceramic magnets were used on either side.
The other magnets are angled at a 45 degree angle, and their moving magnet is composed of smaller neodymium magnets.
They discovered that ceramic magnets are not as powerful as neodymium magnets.
They implemented wooden sticks, which have no effect on the magnetic field, to hold everything in place.
The creation of a motor utilizing this magnetic track technique comes next.
Since creating a spherical track is difficult, using a disk with magnets below is a simpler solution.
These magnets will come into contact with other angled magnets as the disc rotates.
Whether it is laying down or upright, the motor may still function. If the disc spins efficiently, coils can be added to produce power.
To improve the motor, you may mount two discs on a single stick so that each time the disc rotates a little, the magnets will receive an additional force.
Most individuals can make this kind of motor, although it requires some effort.
To ensure dependability, to construct this prototype, use a computer cooling fan.
If an antique fan is not accessible, they may be bought cheaply.
A wooden or plastic spacer disk would be attached to the fan to give clearance.
This spacer would then have a wooden square affixed to it, which I would painstakingly carve into a precise circle using a pencil and solid support.
Even if the disc is not flawless, the positioning of the rotor magnets which may be altered with more pencil markings is more important.
It is important to test alternative magnets with the magnetic track since there might be substantial differences in magnet strength and size.
Optimizing the tracks performance may be achieved by angling the stator magnets at an approximate angle of 45 degrees and modifying the space between them.
Conclusion:
To conclude, Making a motor that works only with magnets is difficult because magnets usually have a balanced magnetic field.
But the Dietmar Hohl motor uses magnets at an angle to make an unbalanced field.
This is a better way to make a magnet motor.
Although we usually think of magnetic fields in a certain way, this is not always correct.
There are new ways to use magnets to make motors.
Two people tried different magnets and found that they could make a good motor.
With careful work, it is possible to make a motor that works using only magnets.
