Related to my previous post - Can anyone tell me the meaning of the term co-energy, with respect to a magnetic system?
It vaguely rings a bell from my school physics many years ago, but I couldn't find a definition anywhere on the web. Even Wikipedia doesn't have an opinion, which is a first!
What I really want to know is the energy stored in my electromechanical actuator when current is flowing. I am modelling it in MagNet. Magnet gives 2 energy results - Magnetic energy and co-energy. These change when I simulate current flowing in the coil. They change by almost, but not exactly, the same amount. I suspect the difference is an artifact of the modelling, and actually they should change by the same amount.
