If you are referring to my statement about the magnet and steel, I am not 
confusing them.  The force being applied to the steel is attempting to make it 
come into contact with the magnet.  Energy is being released by the magnet as 
it draws the metal closer since it is having to work against my resistance to 
that motion.  It would be possible to measure the amount of energy by attaching 
a force measuring scale to the steel part and slowly allowing it to come into 
contact with the magnet.  You would be able to integrate the force times 
distance curve and obtain the energy.

No, if the steel is held steady then no work is being done by definition.  Work 
equals the integral of force times distance moved.  Work was done when the 
steel was moved from far away to the fixed position.

The magnet is doing work on the steel as it accelerates toward it.  Magnetic 
potential energy is being converted into kinetic energy in this case.  This is 
much like work being done on a mass that is moved within a gravitational field. 
 The same equations apply which is work(energy) equals the integral of the 
force times the distance moved.  This assumes that the force has a component 
that is along the path the steel follows in space.  A force that is always 
applied at right angles to the motion does no work upon the object.  This would 
be similar to the motion of a charged particle traveling within a static 
magnetic field.  No work is done in that case.

Any technique that resulted in allowing the relative position of the magnet to 
the steel to be reduced could in principle release a portion of that energy.  
And, more pieces of steel could be introduced to the magnet in like fashion 
where each one resulted in more energy release.  Eventually, the field would no 
longer exit the pile of metal and further energy could not be easily extracted. 
 The total amount of energy available escapes my calculation.  The fact that 
steel is being used in the extraction process might multiply the amount of 
energy that can be obtained as compared to that which is stored in the original 
field pattern.  I am not confident in the later possibility and perhaps someone 
else might know the answer.

Don't confuse force with energy.
