Magnetic forces and many poles

AI Thread Summary
The discussion revolves around the concept of a magnet shaped like a half tunnel with two edges at both the north and south poles. The idea raises questions about whether the edges would repel each other due to their similar polarities and what forces could counteract this repulsion. It is noted that energy is required to push the magnets together, and when they separate, the energy returned is less due to friction, highlighting the principle of conservation of energy. Clarification is sought regarding the shape and its implications for energy work. Overall, the conversation emphasizes the limitations of energy output in relation to input when manipulating magnetic forces.

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
 
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
