TOMI - Theory of Magnetic Instability - 02/04/95

This file was originally posted on the KeelyNet BBS as TOMIBILD.ASC on 02/04/95 courtesy of Glenda Stocks.

The following file contains construction details for the device described in the original file TMIDEVIC. It was built from a dream back in 1978 by Stewart Harris of Las Vegas.

The principle has now been demonstrated by several KeelyNet Associates, all of whom are very excited with the prospects. Needless to say, everyone agrees that a circular version would allow tapping of energy from the magnetic drive.

The TMIDEVIC file was sent to KeelyNet by Glenda Stocks and first proven by Norman Comparini. Norm called me and said his model worked. I then built one and it too worked. From that point, several e-mail exchanges got others involved and now it is taking off bigtime.

This past year, John Searle spoke at both the ISNE (International Society for New Energy out of Fort Collins) and ITS (International Tesla Society out of Colorado Springs). He made reference to his circular track demonstration which could be demonstrated on a desktop.

As I understand this circular track, it consisted of hills and valleys on which was placed a 'roller magnet'. The roller magnet would then begin to circulate around the track under its own power, gaining speed with each revolution. This is the basis of Searl's SEG (Space Energy Generator) and his flying disk. Many KeelyNetters who have duplicated the initial Harris linear magnetic drive also have seen the correlation with the Searl circular track.

The TMIDEVIC file was a general description, this file TOMIBILD (for Theory of Magnetic Instability) will provide complete details to test it yourself.

Stewart Harris had a dream back in 1978 which showed him how to make a magnetic track that would power itself. He built it the next day using cardboard, scotch tape and off-the-shelf disc magnets from Radio Shack. It worked just as he saw it in the dream.

Attempts to patent it were unsuccessful, causing Stewart to put it away since 1978. Within the past couple of years, Stewart decided to put it out on the networks and see what came of it. The concept was mercilessly flamed (insulted and made fun of) on the InterNet. This was from people who did not try to comprehend what was claimed or to duplicate the device. Stewart was very disappointed in the reactions.

Back in early January 1995, the TMIDEVIC file was sent to KeelyNet. It was constructed by several KeelyNet experimenters and found to WORK just as described. The inventor has been notified of our successes and is very much enthused by such positive feedback.

The device is quite simple and has numerous possible configurations. It is based on an anomalous effect relating to the instability of joined magnets. There is a thrust from the magnetic fields causing the moveable roller to push up and over a ramp. Gravity then causes the roller to move down the decline.

It is believed the device can be configured in a circular, see-saw or zig-zag track to run on its own power. By the time you read this, it will hopefully be in production as a novelty toy and probably have been arranged to rotate a shaft for power transfer from the magnetic repulsion.

By all means, do not let this stop you from experimenting with it. The cost will range anywhere from $10 to $30 for the magnets. We here at KeelyNet want everyone to be aware of this, please experiment with it and share your findings with others.

This is a MAJOR DISCOVERY that anyone can build from off the shelf Radio Shack magnets.

Update as of 08/27/99

Recent events have led to some excitement relating to a new phenomena which ties in well with the TOMI. The information is posted at Ohsako's Principle which gives a lot of background in support of the probability for a self running magnetic engine.


When you first insert a roller magnet in the TOMI, you will note the REPULSION of the like poles which causes it to be PUSHED up the ramp towards the NULL MAGNETIC ZONE at the magnet equator known as the 'Bloch Wall'.


The roller will basically fall into the area of LEAST magnetic pressure which is the equatorial Bloch Wall.


The inertia of the roller will carry it past this null zone and into the magnetic embrace of poles which now ATTRACT to PULL the roller the rest of the way up the ramp.

You will note in the construction details below that the magnetic side rails must EXTEND BEYOND THE RAMP to allow the roller cylinder to drop out before reaching the end. If you fail to do this, the roller will flip to one of the sides due to the ATTRACTION of the UNLIKE POLES to each otherss.

This MAGNETIC GRADIENT applies to all magnets because there IS a null zone in all of them. High 'pressure' on either pole that reduces as you approach the Bloch Wall.

In the event of the TOMI, we have a magnetic roller that begins to move under a PUSHING force across the weakening magnetic gradient to the null zone, then inertia carries it into the PULLING zone, where its forward motion continues until it drops off the end of the ramp.

To construct your own TOMI (Theory Of Magnetic Instability) device;

    1)  For the ONE ramp test
           Buy 30 circular magnets (with the hole in the middle) from
           Radio Shack, these cost $1.69 for 5 magnets, so the magnets
           will cost about $10.00
        For the TWO ramp test
           Buy 50 circular magnets (with the hole in the middle) from
           Radio Shack, about $17.00

    2)  Take some stiff cardboard and make two hills (each hill
        consists of an incline and a decline, experiment with the
        angle, about 30 degrees)

    3)  Make three rolls (or five rolls if you are using 2 ramps) of
        10 magnets each (connect the magnets to form 10 magnet stacks,
        kind of like a roll of Lifesavers)

    4)  Tape these magnets together with scotch tape

    5)  The ones for the side of the ramps are called RUNNERS, one
        other 10 magnet roll is used as the ROLLER that moves up the
        incline perpendicularly between the RUNNERS

    6)  On each ramp (incline), you attach one roll of magnets running
        up each side, so that's two magnet rolls per incline and NONE
        on the decline

    7)  The RUNNER magnets on the sides should arranged to be of
        opposite polarity, that is, North at the top on one side,
        South at the top on the opposite side (it doesn't matter which
        side is N or S, only that they are opposing)

    8)  The ROLLER should be placed at the base of the ramp with its
        poles facing like poles on the RUNNERS, since LIKE magnetic
        poles REPEL, this will provide the repulsion you require to
        make the ROLLER move up the incline between the RUNNERS.
For the Harris device, the 'over the hump' necessary for any perpetual motion device is provided by gravity on the roller as it moves down the decline. This effectively 're-loads' the machine for the next upward pass.

The inertia of the moving roller must be sufficient to get it past the attractive end of the guide magnets and over the apex of the incline/decline. This is something you will have to provide for in other configurations if you want to make it 'perpetual'.

To prevent attraction of the roller at the end of its travel, you should have the runner magnets extend beyond the incline, so that the runner drops down the decline and out of the attractive field of the end magnets.

One other tip, the more magnets you stack together, the weaker will be the overall force. A common idea is to create a circle of connected magnets that will provide a continuous acceleration.

It sounds good, but in fact will not work, so don't go out and buy $100s of bucks worth of magnets. Try it yourself by stacking 20 or so magnets together and see how the field weakens.

The following diagrams show how simple it is to reproduce, experiment with it, have fun and we would all appreciate being informed of any improvements you might make.

Make sure that the magnetic cylinders that are placed on the sloped sides of the ramp, stick out BEYOND the ramp about an inch or so. This will let the roller magnet DROP out of the embrace of the magnets. Once you see it work, you will find you can make multiple ramps where the roller will roll up one, then drop into the embrace of the next ramp and roll up to drop off that dominoes..its a neat effect. The hardest part will be to make sure the roller is guided when it rolls up, the roller must be perpendicular to the two side magnets that provide the driving flux.

The entire thing is difficult to get running, but when it is in motion, it reminds you of a row of dominoes falling from a single impulse.
