Discussion Overview

The discussion revolves around the concept of creating a spinning magnet motor with a stationary component, specifically focusing on the arrangement of magnets and the mechanics involved. Participants explore the feasibility of the design, potential energy requirements, and seek visual aids or diagrams to assist in the construction process.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants describe a design where the grey area is stationary while the outer circle spins, with magnets represented by black and red dots.
  • There is a question about whether this design constitutes a type of motor and the necessity of varying angles between magnets and energy input for operation.
  • One participant speculates on the possibility of the system spinning indefinitely if magnets are perfectly aligned, questioning the energy requirements for maintaining motion.
  • Another participant argues against the feasibility of perpetual motion, stating that the system would quickly reach a position of equilibrium, requiring energy input to initiate movement.
  • Concerns are raised about the design resembling a perpetual motion device, suggesting that it may not be a practical endeavor.
  • One participant requests diagrams or references to existing designs to aid in building the proposed motor.
  • A suggestion is made to look at existing permanent magnet motors for guidance.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of the spinning magnet motor concept, with some questioning its practicality and others exploring its potential. There is no consensus on whether the design can function as intended or if it resembles a perpetual motion device.

Contextual Notes

Participants express uncertainty regarding the energy dynamics involved in the proposed design, particularly in relation to the alignment of magnets and the energy required to maintain motion. The discussion does not resolve these uncertainties.

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.
