Where does the heat go? The spring will have a much larger surface area to dissipate the heat. Maybe surrounding the magnets with a copper tube will conduct some eddy currents.
- notacoward 8y agoA lot of science museums have a display showing how magnets and copper pipes interact. In short, because of Lenz's Law, the magnet's motion induces an opposing magnetic field in the pipe ... which suggests another possible way to make a pogo stick with the right kind of resistance curve as well as addressing the heat issue.
- rubatuga 8y agoThis means the kinetic energy is lost to heat, which is not good for a pogo stick
- madengr 8y agoYes, but there will always be some heat loss, and the magnetism is lost with heat. I’m just assuming the pogo stick will drastically fail when the magnets get hot enough.
- contravariant 8y agoA mechanism that absorbs any kinetic energy would make for a very disappointing Pogo stick.
- notacoward 8y agoIf it absorbed all of the energy that would be a problem, but any child who has seen one of those science-museum displays I mentioned can tell that's not the case.
- contravariant 8y agoYou don't really want a pogo stick to absorb any energy, it'd be like trying to make a pogo stick out of mud.
