Magnetic is a force not energy.

Energy is
(a) Work done on a charge by applying a magnetic force Fm and moving this charge distance S. The trick is if either a magnetic force or electric charge must move or all bet are off.
As the charge Will accelerate under a magnetic force its kinetic energy will change.
(b) Work done on moving say iron body distance d and by applying force Fm. The trick is the magnetic force does not work well over a distance. And just before the iron body hits the magnet it would have the maximum kinetic energy.

So again it is a force not energy
Energy or work= E=d F
d- distance/path
F force applied along path d on that object

I hope that helps

Neither. Magnetism, more correctly magnetic force, is a force, not energy. For example fm = q(v X B) is the force on a charge q moving with velocity v through a magnetic field B. As gin pointed out, if the charge is not moving, so that v = 0, there will be no magnetic force. If that charge q is moved by the force fm some distance d, we have work E = fm dot d and that is energy. Since movement is involved here over d, I'd say that's kinetic energy. My point here is that you differentiate between force and energy. They are different. Force is a push or pull, and energy is the capability to do work or cause a change.
