Motor drive a coil in a magnetic field to power itself?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of constructing a motor that could power itself by generating excess energy through the motion of a coil in a magnetic field. Participants explore the implications of energy transformation and the concept of perpetual motion, questioning whether a smaller input of energy could yield a larger output.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes the idea of a motor that generates excess energy to charge a battery for its own operation, expressing uncertainty about the calculations involved.
  • Several participants assert that perpetual motion machines are impossible, indicating that the proposed concept violates fundamental laws of physics.
  • Another participant seeks clarification on whether a smaller amount of energy can be used to collect a larger amount, emphasizing that they do not intend to propose a perpetual motion device.
  • Concerns are raised about energy transformation processes, highlighting that all transformations incur losses, which would prevent the proposed system from functioning as intended.

Areas of Agreement / Disagreement

Participants generally agree that the concept of a self-powering motor as described is not feasible, with multiple viewpoints emphasizing the impossibility of perpetual motion and the inherent energy losses in transformations. However, there is some disagreement on the interpretation of the original proposal and its implications.

Contextual Notes

The discussion touches on the limitations of energy transformations and the definitions of perpetual motion, but does not resolve the underlying assumptions or calculations that would be necessary to fully evaluate the proposal.

Hello Friends,
I have been wondering, is it possible to construct a motor, and attach a coil to it, such that with the motion due to the rotation of the motor, it generates a excess of energy that can be used to power the motor in turn, basically, could i use the excess to charge a battery that then is used to turn the motor. Short of doing the calculations i am honestly not sure.

No. Perpetual motion machines are impossible and discussion is forbidden at PF because it's a waste of time.

This was not intended to be a perpetual motion device, if this breaks any laws of physics, please help me understand. What I am trying of to clarify on a more fundamental level, is if a smaller energy can be used in a process that collects larger amounts of energy, not create.

Collect from where? If you add a mystic energy source to your experiment, then it will be the same as maintaining the motor with it.

Every transformation from one form of energy to another causes losses, e.g. in terms of heat or radiation. So there is no way to do what you proposed. That is why this topic is excluded by our rules. It's simply not possible.

Thread closed.

As part of closing this thread, here are some links from the PF rules (see INFO at the top of the page) about forbidden topics here. Follow those links to do some reading about why what you are asking about cannot work. :smile:
