Discussion Overview

The discussion revolves around the concept of a magnet motor that utilizes magnetic forces to simulate a pendulum motion, with the aim of achieving propulsion through the equalization of forces over time. Participants explore the mathematical modeling of dynamic forces involved in the system, including the interactions between various magnets and the body they are attached to.

Discussion Character

  • Exploratory
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant describes a concept for a magnet motor that mimics a pendulum, proposing the use of magnetic attraction and repulsion to reset to a starting state.
  • The participant outlines the forces acting on four objects (Weight Magnet, Rebound Magnet, Electro Magnet, and Body) and presents a pseudo simulation of their interactions over time.
  • Another participant questions the purpose of the device, referencing existing technologies that use electromagnetic vibrators.
  • A follow-up response suggests that the motor could provide thrust by equalizing forces over time rather than instantly, referencing a pendulum motor as a conceptual basis.
  • The original poster expresses uncertainty about how to mathematically model the N-body problem of magnetic forces acting at dynamic distances and seeks assistance with the math involved.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the feasibility or purpose of the proposed magnet motor, with some questioning its novelty and others exploring its potential for propulsion.

Contextual Notes

The discussion includes various assumptions about the behavior of magnetic forces and their interactions, which may not be fully defined or resolved. The mathematical modeling of the proposed system remains unclear and is a point of confusion for participants.

The Idea

The idea is similar to a pendulum in motion. I noticed that it was possible to shift the weight towards a single direction causing an immediate force, which equalized over time. I figured I could use magnets to simulate a pendulum and also reset to the starting state using both magnetic attraction and repulsion.

Here is the concept: http://imgur.com/pK3UHhj

The Math Problem

There are 4 objects that have dynamic forces being applied. We'll call the objects Weight Magnet (W), Rebound Magnet (R), Electro Magnet (E), and Body (B). The Rebound and Electro are welded to the Body, so any forces must act on the combined mass of the three objects. The W and R magnets are static in strength, and the (E)lectromagnet can be scaled to any strength.

Here are all the variables:

  • Mass - W, R, E, B
  • Static Magnet Strength - W, R
  • Electromagnet Strength - E
  • Distance between - W and R, W and E
  • Oscillation Frequency - E
  • Time - W
  • Force - W, R, E, B

The pseudo simulation with looping Time period [1,9]:

  • Time(1) -- E repels W, outward force applied to E and W
  • Time(2) -- W force at 90%
  • Time(3) -- W force at 50%
  • Time(4) -- W force at 10%
  • Time(5) -- R repels W, outward force applied to R and W
  • Time(7) -- W force at 80%
  • Time(8) -- E attracts W, inward force applied to E and W
  • Time(9) -- W at distance=0 with E

I would really like to map out the simulation with math more accurately, and am quite unsure where to begin. What confuses me is the N-body problem of magnetic forces being applied at all times at dynamic distances. Any help with the math would be appreciated, thanks!

Electromagnetic vibrators are already common components in cellular telephones and adult toys for women. What is the point of this device?

Propulsion. The hypothesis is that if the motor equalizes forces over time instead of instantly, it can provide thrust.

The concept came from this pendulum motor:

Here is a figure of the forces: http://i.imgur.com/YTa0ST8.jpg
At t=1, C will repel B towards A.
At t=5, A will repel B back to C.
At t=7, C will attract B

I'm not a physicist, so I need help in figuring out the math to evaluate if there is the slightest thrust in any direction.
