Consider a situation where you have a charge at rest in a uniform magnetic field.A sharp impulse is given to the charge in a direction perpendicular to the magnetic field,if the velocity is high enough the charge which starts revolving in circular path should behave like a current carrying coil.Now we know that a current carrying coil has a magnetic moment 'M=I*A',and we also know that this magnetic moment will give an energy to it which is equal to 'M.B'.My question is what happens to conservation of energy in this case because the work done by impulsive force only gives it kinetic energy but you have another magnetic field interaction energy as mention above.

The energy of the magnetic moment is not in addition to the kinetic energy, but rather another way of expressing the same energy.

Can you please justify your statement?
