Partnered Output Coils - Free Energy

[minnie]

  I want to try and find out if anybody is good at physics.
What I want to know is with the Pluto mission would the clock
on board have"lost" time compared to here on earth.
If the thing went at 16.316 km/sec and there were 10 years
worth of seconds what would happen?

If we have a set input energy that remains the same in both test,and yet we get a higher energy output from the second test simply by adding a PM,-if not from the PM,then where did the extra energy output come from?as the only change between the two test is the addition of the PM.

Ah but you don't.  The mistake that you make is that you are evaluating a continuous power level where most of that power*time integrand is spent heating the wire in your electromagnet, dwarfing the energy that it took to magnetize.  It is the energy that goes into the magnetization that you want to know but are not measuring.

Ok,lets do it ass about.
We want to achieve say a 10 Lb pull force on that spring. With the ferrite block in place,we may need say 12v @ 2 amp's applied to our electromagnet to achieve such a force. We then replace that ferrite block with a PM of the same size,and we now find that we need only apply say 6V @ 1 amp to achieve the same pull force on that spring. So the work done against the spring is the same,but we need only apply half the energy to that electromagnet to achieve the same work done.

There is law about conservation of energy.There is no law about conservation of work.

The electromagnet fields strength remains the same.
This dose not answer the question posed in my test.

Hopefully these timing diagrams will help make the situation more clear.  The energies that we are interested in are the: energy in the spring which you qualitatively have, and the energy needed to get more or less energy into the spring.  Over any significant period of time the energy that is going into the electromagnet is going to asymptotically approach:  V/R_WINDING*T.  But once the magnetic field has been established (and the spring has stabilized) there is no more energy being added or removed from the spring.  The work that goes into the spring comes from establishing the magnetic field.  Because we don't have superconductors, we are then stuck feeding the I²R losses of the winding.

In the drawing below you can see that the forces are different using:  a ferrite keeper, or a PM aiding or bucking the electromagnet.  The current profile and therefore power and energy up to the point the magnetic field stabilizes is different for all three cases.  So: literally all you have done is to set up a situation with a stronger magnet, and it takes more energy to magnetize it.  There is a component of work that is also performed moving the PM into place.  The experiment does not measure the electrical energy used to magnetize, or the work performed placing the PM.
