    Can a setup of magnetic fields be used to perpetually move a generator's rotor? Or a construct of magnets and other pieces, perhaps using gravity to help the process.
    Please think in 2D and 3D. Thx!

    the simple answer is no. whatever you do you can't milk energy from a system and have the system remain intact indefinately. it's just a basic law of the universe based on our observations, you don't get something for nothing.


    physics: accurate, objective, boring
    chemistry: accurate if physics is accurate, slightly subjective, you can blow stuff up
    biology: accurate if chemistry is accurate, somewhat subjective, fascinating
    religion: accurate if people are always right, highly subjective, bewildering

    also to note, please correct me if I am wrong, is that if you choose to use such an energy source you have the problem of Electromigration, which in real laymans terms could be described as the removal of materials in the system due to electron flow.....................similar to what happens when you rub any 2 objects together...........

    Fatman, even without electromitigation, making that kind of machine would be enormously cost-effective. However, as Saul said, what you are proposing would be perpetuum mobile, which is impossible. If you would try to make anything of that kind, it would eventually end in a position of balance.

    thanks guys, nevertheless I'll continue studying electromagnetism with the same amount of ambition :wink:

    Get a good book on the subject and read it.

    Marions Classical Electromagnetic Radiation is a good undergraduate text, as is Griffith's book Introduction to Electrodynamics. The standard graduate text is Jackson's Classical Electridynamics.

    correct - but what I was getting at was that it would eat itself to run, which would shorten the life of the item.

    A well balanced machine is the best you could achieve and is what most people create when they try to make perpetual motion machines. To get any usable energy out of it would be impossible, everything we have encountered so far has to eat in order to get energy, the sun consumes itself and biology each other to survive, and the sun has a limited lifespan............excuse the analogy.

    there is one machine using cavitation to generate heat which apparently gives out more heat than the energy put in, I have still to investigate it..........it does look more plausable than the other stuff but as always one needs to be sceptical on these issues.......

    my next question................how many people ask questions on this site about perpetual motion? One born every minute i guess..........my apologies if anyone takes that the wrong way.............
