    Where does a magnet get its power?

    Why doesn't this source run out?

  3. It doesnt have any power, stick it in front of a stationary coil, it
    will not "create"any electron flow in the coil.

    But if you move the magnet infront of the coil, there will be electron
    flow in the coil, which could power something, so "you" provided the
    power

  4. I can only differenciate your question.

    It is of premade structure, made in the time before the physics began
    as we know and live them.
    Similar to Gold, made in the inner core of the Sun, with a temperature,
    which is nowhere else available as in the sun itself. Therefore it is a
    so much burned down spare-material (at 6mrd degrees Celsius), that it
    cannot be transformed (oxidizing... which is a kind of burning, but too
    slow for our reception) any further.
    This also means, if you wish to make gold, you have to find such a hot
    source as it is in the sun. The other ingredients are mystic.

    And a magnet to make, would also need the reactions which made it.
    Maybe it was the Explosion of our Mother Sun, because the Sun is the
    only Object known, which can polarize its poles on the same point. Who
    knows how some irons had reacted to that inimitable moment.


    Hmmm, the iron (a normal dumb piece of iron) is also not running out.
    Why should the magnet do so?

    It doesn't have any.
    See above.

    From the atoms being aligned. it magnifies one of their energies in
    a like plane.
    The word for today is entropy.

    Maybe one day it will... when all atomic particles stop moving.
    Not likely any time soon though.

    Man, what a dick!
     
  8. so all the usenet will turn to 0 K.

  9. Yes, it's also not running out. ;)

    There is energy stored in the magnetic field around a permanent
    magnet.

    That energy DOES run out at high temperature, the so-called 'Curie
    temperature'
    named after Monsieur Pierre Curie, but at low temperatures there is a
    quantum effect,
    sometimes called 'exchange force', sometimes called 'Hund's rule', that
    favors aligned electron magnetic moments.

    So, the energy in the magnetic field is stuck, and doesn't run out,
    except in nonmagnetic
    materials and at high temperatures in magnetic materials. Some heat
    disappears when
    the magnetic material becomes magnetized on chilling below the Curie
    temperature, which
    provides the stored energy.
     
  11. Power is work per unit time.

    Work is force times distance.


    A magnet has an attractive force, but the distance is limited, once the
    pieces click together, you can't get any more work out of it. Then you
    have to pull the pieces apart, supplying work to return the parts to
    their original states. And it's just as much work to get back to
    original state as you got from the first attracting part of the cycle,
    so there is no net work done.

    Now there is a clever engine, where you heat the magnet above its Curie
    temperature, which lets you move the pieces apart with little or no
    work. But the dang law of conservation of energy seems to hold
    anyway-- it takes much more heat to do this than you ever get back out.
    Dang.
     


  12. Hi!


    Pulling energy into something to find something new?

    The world would not be technically so far, when every unknown
    materie/science had been processed with auxiliary energy.

    E.g. electric eel.

    think of magnet like a rock with a billion little micro springs
    attached to it and everything magnetic near it, there is stored energy,
    but if you use it you have to add work back into it to restore it, a
    magnet is just a vessel to hold potential energy

    gravity works the same, except the springs are attached to everything
    around it

    Wrong - gold gets made in supernova explosions (by neutron capture from
    iron, along with every other element heavier than iron).

    Our Sun doesn't make gold, and we wouldn't survive the event if it ever
    did - but it won't. The earth won't survive the Sun's transition to a
    red giant on the way to becoming a white dwarf, but we should be able
    to lead before then (if we haven't gone extinct or evolved into
    something very different by then, as seems very likely - we've got
    another five billion years to go, and it only took 500 million years to
    get from the most primitve multi-celled animals and plants to us.)

    I've snipped the rest the posting - it seems to be just as wrong.
     

  15. We can only hope! ;-)

  16. This is just Theory. There is an other Theory without a supernova,
    called Mayas.

    You should learn the basics.


    Good Bye, DR. Wrong!

  17. Gets made.... pah, :))). ts, ts, typical.

    1980 they (official status of the known and accepted science) told me,
    the big bang is the start-point of our sunsystem. Now we know it's over
    twenty MRd Years old and no end/beginning in sight ;-)


    Gold might 'have been' made in/while Supernova explosions...etc.

    We could "make" gold from mercury, but the process would be more
    costly than the product.
