Discussion Overview

The discussion revolves around the concept of magnetic forces, specifically focusing on a hypothetical magnet design that features multiple poles and edges. Participants explore the implications of this design on magnetic repulsion and energy transfer, raising questions about the feasibility of using these forces to perform work.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant proposes a magnet shaped like half a tunnel with two edges on each pole, questioning whether the edges would repel each other and what forces would counteract this repulsion.
  • Another participant asserts that the energy required to push magnets together is equal to the energy released when they separate, noting that friction results in a net loss of energy, referencing the conservation of energy principle.
  • A different participant expresses confusion regarding the initial proposal, indicating a lack of understanding of the described magnet shape.
  • Another participant reiterates that regardless of the shape, the work output cannot exceed the work input when bending the magnet.
  • The original poster acknowledges the feedback and expresses intent to clarify the shape with a name or image.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of the proposed magnet design or the implications for energy transfer, with multiple competing views presented regarding the nature of magnetic forces and energy conservation.

Contextual Notes

There are unresolved assumptions regarding the specific shape and properties of the proposed magnet, as well as the definitions of work and energy in the context of magnetic interactions.

i had this idea of a magnet, if u bend the magnet, so that it has 2 edges on the north pole and 2 edges on the south pole, just like half a tunnel, i don't know the name of the shape, but suppose it has 2 edges on the north pole, won't the 2 edges repel each other because they are positive, what forces act against the repelsion force, can we use that force to do work or energy.
thanks

btw when i meant 2 edges its just like a U Magnet but in a shape of cylinder-half a tunnel-

No. It takes x amount of energy to push the magnets together and you get x when the fly apart. Actually, you get less than x because of friction. Sorry, conservation of energy.
 
i didnt quiet get you!m its just one magnet
 
I don't understand the shape you are describing, but in any case, you can't get more work out than the work you put into bend the magnet into that shape.
 
oh, yeh i think i get the idea, anyways i'll try to get the name of the shape or picture it for u, thanks anyways
