Creating a Spinning Magnet Motor with Stationary Grey Area: A DIY Guide

AI Thread Summary
The discussion centers on creating a spinning magnet motor with a stationary grey area and a rotating outer circle, featuring black and red magnets. Participants express difficulty finding diagrams or resources online, often encountering basic science projects instead. There is skepticism about the feasibility of the design, with concerns that it resembles a perpetual motion device, which is not practical. The consensus is that energy would need to be input to initiate movement, as the magnets would not sustain motion on their own. Overall, while the concept is intriguing, it may not yield useful work or be worth significant investment of time.

the grey area is stationary and the outer circle should spin.. the black and red dots are magnets

is there a diagram anywhere online or something? i tried searching and i couldn't really find anything except 6th grade science projects :p
and before anyone asks... noooo this isn't homework lol

Is this a type of motor? If so, you would need some way of varying the angles between the magnets and a means of putting energy into the motor.
 
i guess it could be a motor :p

so it IS possible? if the magnets were aligned exactly, would it need any energy to keep it spinning, or would the + - pull/push on the magnets keep it going?
 
No, it would not. It would quickly move into the position shown and then stay there, putting up a fair amount of resistance to any movement. So, you would have to put in some energy just to make it spin and it would not do any useful work for you.

The energy in magnets is generally unavailable; you can sort of think of it as being similar to the Earth's gravitational potential energy which is only available by being placed in a certain position. Once that position doesn't exist, you have to do work to put it back.

This looks suspicously like a design for a perpetual motion device.

If you're in this for entertainment, great. But don't put valuable time into it.

(And don't expexct this thread to stay open long.)
 
so no one knows of a diagram or something i could look at to help me build this??

and its not perpetual motion, though that would be cool :p
 
Sure. Look at any permanent magnet motor. TVP45's post is very helpful if you read it completely.
