where a is the capacity value of the system, is the number of turns of the coil, and
( / )
is the instantaneous change in flux value. One part of this energy should be returned to the system by the battery, but this is done in Position c, where the flux value is the least, while the collapse is done when the flux is at its maximum value. The increase of the flux value is realised by the work of the flux lines, and not by the input current. With a huge volume of copper wire solenoid, the capacity value and the collapsing power is considerable. (It seems that Mr. Newman used it to light up a fluorescent tube.)

in the shaded area, where we have a high permeability value and very low hysteresis losses. By braking the rotating shaft, we go from Position a to Position b. The solenoid current will slightly increase, but this is compensated by a stronger magnetic field. We can state that only the special characteristics of ferromagnetic materials (soft and hard) allow us to suggest that a 110% efficient electromagnetic device is possible.
