grdg Posted July 12, 2022 Posted July 12, 2022 good evening, I am currently working on a device. I'm still at the modeling stage. I make this publication in order to be able to exchange with scientists or experts because I have the impression that certain parameters escape me but I cannot see which ones. I apologize in advance if my post is inappropriate. Cordially
Halc Posted July 12, 2022 Posted July 12, 2022 (edited) I presume it's supposed to turn despite no net torque applied. That can't work. Sure, you have a force at application points pushing it counterclockwise, but the torque applied between the plate and same points of application balance that, pushing it clockwise. No motion will result. Rule 1: Perpetual motion machines violate physics. Can't be done. Edited July 12, 2022 by Halc 1

I suggest you study Halback arrays. https://en.wikipedia.org/wiki/Halbach_array You might be able to knock up a home made prototype using fridge magnets to study the mag fields. However remember that conventional electric motors work on somewhat similar princples and all of them have trouble starting because of symmetry. So they all have various arrangements to provide an initial impulse and then rely on mechanical inertia to take the rotor round to the next driving position.

You have omitted the torque that is also exerted at your "point of application of the repulsive force". This will be a clockwise torque. Alternatively, taking your brown construction as a rigid body, it should be obvious that applying two opposite forces (whether from magnets or anything else) along the diameter will simply tend to squeeze it and will not cause any rotation, regardless of its shape.
