    Literatures which dealt with electromagnetism are concerned mainly by solids that have electric or magnetic properties. Such analyses is ineffective when dealing with a general thermodynamic system that may involve fluid flow while it is tied by conservation equations of energy and momentum and subjected to transfer of heat, electric, magnetic and mechanical energies. Most of them ignore also the entropy flow associated by the flow of electric and magnetic energies. Such truncations paralyze explanation of different electromagnetic phenomena. In my article of the title: An Advanced Review of Thermodynamics of Electromagnetism., http://ijrsset.org/pdfs/v3-i6/2.pdf, the Maxwell’s equations of electromagnetic waves were casted into an energy frame of reference that replaces the time by entropy. Such transformation led to plausible definitions of the natures of electric charge, magnetic flux, energy quanta and the photovoltaic effect. Such definitions explained the discovered Tesla’s wireless power transmission as “Electrical Radiant Energy,” the MIT discovery of wireless power transmission of the magnetic flux as “Evanescent Waves.” The introduced review led also to new discoveries in the field of photo-voltaic cells and optical fibers, and to delete discrepancies in the SI system of units. Such approach was applied also in different citations for further applications as the failure analysis of transformers and power quality assessment.

    hey,can any one tell me ,
    can we map electromagnetic feilds…?
    can we calculate the intensity of em feild in a medium or in free space/atmosphere…?
    how to find whethere the electromagnetic feild
    around us has increased or decreased …..?
