Re: Magnets = Energy?

Interesting. If gravity is a form of energy and the magnets are pushing
against it that would suggest energy in the magnet. Ok, I know this
is contradictory. Let's examine it this way. It takes a massive amount of
energy to align the magnetic domains. Energy can't be created or destroyed.
Electrical energy dissipates in several ways, typically heat.
In the case of charging a magnet what happens to the electrical energy?
We know it was not destroyed or converted to heat. It was used up creating a
temporary magnetic field to charge the magnet to a permanent state. I would
argue that a magnetic field is energy except that it takes
energy to get the energy out. Example would be a permanent magnet generator.
Remove the magnets and there is no electrical output. You simply have a
spinning mechanism. Not trying to break any law's here.

I have 2-100 pound pull magnets. They are in repel mode.
The top magent is mouted on a round one inch thick steel plate nside of
a
PVC tube. The other magenet rests at athe bottom of the tube. So far it
suspends 50 pounds about 3 inched in the air. If I try and hold 50 pounds
against gravity I become a litte tired. This suggets I am expelling
energy.

Correct.

Is the pair of magents not doing the same thing?

No. All of the energy that you are expending in holding a weight goes
into heating your body (most of the heat going into the muscles that
are used to hold the weight. None of the energy is delivered to the
weight.
The magnet is no more "expelling" energy than a shelf with a weight on
it.
