Possible simple magnet motor

[Low-Q]

Hi!

The rod magnet will be forced to the left in this picture. The disc magnets is provided from loudspeakers where equal poles are facing each other. I have just tested this by helding a neodym magnet between these disc magnets. I have no rotating device, but hopefully the force will make the disc magnets to rotate.

Hi,

Are you aware of this idea from Stefan:

Some years have passed I have not heard any positive results, Stefan?

Hi Gyula

This is not the same thing. However it has a few similarities. Stefans invention does not provide any force in any of the directions, as the sum of the rotating magnets total magnetic field is zero - the fields are not only running from north on one magnet to south on the other magnet, but also running from north to south on the same magnet. The sum of the field directions are therefor canceling each other out. The intention however, I believe is to make a circular magnetic field like those found around a conductor where it flows DC current. This is not possible by arranging the rotating magnets the way Stefan is doing.

I do not expect that my way to do it works, but the thaught is that presenting equal magnetic poles, by the disc magnets, to each ends of the magnet bar - where you in fact have a circular magnetic fields in each end - would force the magnet to move in only one direction.

The origin of this thaught, is how a loudspeaker motor works. With neodym magnets available, many producers make the motor system with underhung design, where the voice coil is much shorter than the hight in the magnet gap. This voice coil is moving forward and backwards in an uniform magnetic field depending on the current polarity. If the magnet gap is infenitly high, the voice coil would then move in one direction constantly when DC current is used. So if the hight of the magnet gap was a closed circular loop, this voice coil would move around forever as long as DC current flows in it. So by replacing this electromagnet - as the voice coil is - with a permanent magnet, I hoped to make a constantly moving system without any need of external power supply.

Hi All
This may be related, I saw these years ago and could never figure out how they work. It looks like an electromagnet next to a disk that makes it spin. Dose anyone know?

This looks like a DC-current generator, but runs as a motor instead. If you connect a conductor with one polarity to the edge of the disc, and the other polarity to the center, the disc will start spinning when a permanent and uniform magnetic field is going throuhg it. However, I believe this is not much related to the device I have presented previously in this thread.
