Can opposing magnets be used to store a reactive force?

The spring capacity size and weight is off. Can opposing magnets be used to store a reactive force in a controlled manner for release? These clock guys blew me out of the water. They were sharp but closed minded. Shame.
I need some type of alternative substance to store energy in. Concentrated like oil is.But rechargeable and inexpensive. I know you guys all think out of the box. Go search the past posts of all areas for the person or idea. It's out there some where. Maybe something composite in nature.

#-Link-Snipped-# , Can you please explain the question in greater detail? What exactly do you want to achieve here? The moment I read your question, I remembered my professor showing me a magnetic fluid which changes its shape and almost becomes "crystalline-like" when moved into a strong magnetic field.

I am looking to replace a conventional metal spring to store and release energy.

Oh, I see what you plan to achieve. Well, The problem with magnetic fluids (ferrofluids) is that they appear to return to the non-structured state immediately after the magnetic field is removed. Such a quick release of energy is not desired, since springs can be used to store PE and the rate of energy release can be precisely controlled.

I assume, if the intensity of the magnetic field is gradually decreased, we can extract power out of a mechanism involving a magnet and a ferrofluid. In any case, here is something I found on Wikipedia:

Do look under Mechanical Engineering Application section. It says ferrofluids can be used as a semi-active dampers.

Paint a picture of the application your envisioning with this ferrofluids. I am trying to drive a small electrical generator for a cook stove. Keep in mind the expense. But once production is up at 100,000 units the cost can be driven down. Ok I will be off line for the day shortly. Need to make money lol
