Hello, tektrical,
I never heard of paramagnetic energy, what do you mean with that?
Energy is the ability to do work! For example magnetic energy become voltage when current is interrupted in a coil... or when it's forced thru it... the change in magnetic field strength is know to be the cause of the voltage in a coupled coil.
Energy is force multiplied by the distance where also there is a angle component .
Só obviously when the angle is 90 the work is zero!!!
When we press a spring it will increase the force for every distance we press it and we here is the energy it has and how we can view it will pull whatever is in its way if collapsed....
A capacitor is considered a spring because for every charge you put into it it will increase its voltage requiring that to add every charge you need to increase voltage applied too.. so like a spring the greater is the displacement the greater is the back force and so on...
A coil is representation of inertia because current flow will want to keep flowing or to not flow until there is no more changing magnetic field to impede the change .
Another kind of comparison we could do is:
imagine one Pearson with its feets on the ground pulling another Pearson that is over a light small car...
Now imagine that they are pulling each other by their hands.. so their arms tension represent the back emf a coil will
