One of the things I have learned is that imagining the fields as a bunch of lines closely circling the magnet just isn't reality. It's more realistic to picture the fields as huge balloons surrounding each magnet. For instance, take two neos in repulsion and slide them toward each other on a table. When you begin to feel some resistance they are a considerable distance from each other, and the actual fields are quite a bit bigger than that. Trying to build a smallish magnet motor is like trying to replace the rotor and stator magnets with oiled balloons and squeezing them together into a motor shape. It just will not work. Try the balloons, the rotor acts exactly like every magnet motor out there with the rotor balloon coming to rest between two stator balloons. I think if a successful magnet motor is ever made, something will have been done to keep the fields separate and to direct and confine each field to a much smaller area. That and the size of the motor will have to be big enough to prevent separate stator fields and separate rotor fields from occupying the same space. An interrupter to break or reverse the field action between the rotor and stator at the right time appears to be another necessity. Sometimes it seems a hopeless task, but maybe.... --------------------------- 'Tis better to try and fail than never try at all

Good observation, I did an experiment with two 1" x 2" N35 neo magnets and found they could effect each other even at an eight foot spacing.

Another good observation and the magnetic field becomes more spherical with distance. So we can distort the field however the most natural form found in nature is a circle or sphere. There are quite literally no straight lines found in nature for a very good reason. The inertia of an object tends to move it in a straight line however any "external force" causes the path to curve. Thus all form is a result of internal versus external forces producing the geometric forms we see.

An interrupter to break or reverse the field action between the rotor and stator at the right time appears to be another necessity. From experience I found most asymmetrical forces were the result of a delayed response. That is some variable delayed an equal and opposite reaction from occurring. Think of it this way, magnet A approaches magnet B and is repelled however the repulsion reaction is delayed so it occurs at a later time than expected. Thus the repulsion is weaker than expected at one point but then becomes stronger at another point later. As a whole the action/reaction is equal and opposite however not within a given region because the force is delayed. This may help...https://www.electricaldeck.com/2020/07/construction-and-working-principle-of-shaded-pole-induction-motor.html Note how a "shading coil" on a shaded magnetic pole can delay a portion of the magnetic field causing an asymmetric force and rotation in a given direction... Eureka!. Understand the process of invention is not all that difficult. We see one effect then at some later time we see another effect then we connect the dots. This is how we invent new things, we look at many things objectively for what they are in reality then start connecting the dots to produce something unique from our own perspective. However if we can only see things from others limited perspective then were not inventing anything... it must be new to us and unique.
