According to the equilibrium equation of magnetomotive
force of the transformer, if the core loss current is neglected, there's
 applied SERS and magnetomotive
enrichment to identify TNT,
After operation, the current in the winding and, accordingly, its magnetomotive
force (MMF) are reduced, but the armature of the electromagnet remains in the final (brought) state, since, at small gaps, the traction force is usually superfluous even at small values of MMF.

It is assumed that the windings are distributed sinusoidal, so that all higher spatial harmonics of the magnetomotive
force can be neglected.

Space harmonics in the armature winding magnetomotive
force (MMF) distribution and time harmonics in the current waveform, together with the harmonics in the air gap permeance function due to slotting, create field components which do not rotate in synchronism with the rotor.
In addition, the least magnetomotive
force strategy was investigated to enhance the availability of winding currents and to decrease the torque ripple and stator vibration .

The following expression can be derived according to Ampere's circuital law that the magnetomotive
force around a closed path is equal to the total current enclosed by the path:
In Figure 2, [R.sub.l1,2] denotes the magnetic reluctance of the rod within each loop formed by GMM and PM patches alternatively; [R.sub.g] and [R.sub.w] denote, respectively, the magnetic reluctance of the air gap from GMM bar to wall and the reluctance of wall; MMF denotes magnetomotive
force provided by PM; based on Ampere's Law, the above parameters could be expressed as
