Simple Experiment: Extraction of Energy from Permanent Magnets

[Low-Q]

Thanks Forest. Actually the german wikipedia entry on magnetism even says "Every magnetic Field contains Energy." Although wikipedia often isn't really helpful ^^.


See it this way: if you put two magnets into a glass pipe in repelling order, the top one will float above the bottom one at a certain distance. If you replace the bottom one by a much stronger then this distance becomes larger, simply because the repulsion forces add up.


Now, it is certainly possible to limit the current draw as desired, and finally ending up just like in the pipe example with two repelling forces, that are added together.

Potential energy. Not energy. If you put a magnet inside an insolated compartment, will it heat up? No.

YEAH FOREST NOT EVEN CLOSE MY CIRCUIT THE PM  IS
ENCLOSED IN AN IRON CORE, NOT VISIBLE...LOOK AGAIN AT MY
DESIGN..

if you want to patent then, yes it is different , but the principle used is the same, look at attached picture when Willis manipulated with magnetic field distance through core ,using coil at the end of stack of magnets attached to iron core

FORREST IT COMPLETELY DIFFERENT , WILLY PM IS NOT SHUNTED WITHIN THE IRON CORE .
MY VERSION WHEN THE ROTOR APPROACHES THE STATOR THERE IS VERY LITTLE MAGNETIC REPULSION,
IT AS IF TWO PIECES OF SOFT IRON CORE APPROACHES EACH OTHER.. WILLYS HAS THE PM AT THE END OF THE CORE
AND ACCORDING TO YOUR PICS THE ROTOR HAS EXPOSED PM ON IT.. DIFFERENT TOTALLY DIFFERENT..

What is the potential is a field that results from self-magnetization?
and where does this "energy" come from?


I would argue that there is no more "potential energy" in a field than
there is in a spring.
Unless, and except when, the forces CAUSING the field are the result of
a reversible process.

On another note: the interactions between two or more fields
can result in energy transformation from a source,
to a reference point from our perspective.


That is to say, "energy" does not come from the magnets,
except by a reversible process which destroys the magnet.
However, magnets can be used to convert energy.
From mechanical to electrical, or vice versa.
