SUMMARY

The discussion centers around the concept of generating energy using two magnets in a chamber, one positively charged and the other negatively charged, connected to a generator. The idea involves allowing the magnets to move closer together to pull a cord attached to the generator, then using an insulant to separate them again. However, participants emphasize that this concept fails due to the requirement of external work to push the insulant, which counters the energy generated, thus violating the principles of perpetual motion machines.

PREREQUISITES
  • Basic understanding of magnetic fields and forces
  • Knowledge of generator mechanics
  • Familiarity with the principles of energy conservation
  • Concept of perpetual motion machines
NEXT STEPS
  • Research the laws of thermodynamics and their implications on energy generation
  • Explore the mechanics of generators and how they convert mechanical energy to electrical energy
  • Study magnetic field interactions and their effects on motion
  • Investigate the concept of perpetual motion and why it is deemed impossible
USEFUL FOR

Physics enthusiasts, engineering students, and anyone interested in the principles of energy generation and the limitations imposed by the laws of physics.

I know this is probably wrong and that my understanding of physics is basic. But figured id just share a quirky idea I had and see if anyone can explain to me why it wouldn't work.

O.k. Imagine two huge magnets in a chamber. One is positively charged and one is negatively charged. And they are kept apart some distance and attached to the back of the magnet on top is a cord connected to a generator, which it will pull. Then they let the magnets try to get close to each other. So that as the magnets move, the cord is pulled and work is done. Then when the magnets get close to each other, an insulant is pushed in between the two. So the magnets drop back down to their original position. Rinse and repeat.

You are forgetting that you have to do work when you push this "insulant" to shield the magnetic field. Try it! You'll feel an opposing force against you pushing this in between the two magnet. It is the same as if you're pushing a magnet into a solenoid.

This forum really isn't the place to try and promote perpetual motion machine. In fact, no part of PF is.

Zz.
 
I wasn't trying to promote it, just asking why it wouldn't work.
