Innovative definitions.of th. electric and magnetic diffus.vities.th.ough.conducting mediums.and innovative diffus.on equations.of th. electric ch.rges.and magnetic flux are verified in th.s.article. s.ch.innovations.depend on th. analogy of th. governing laws.of diffus.on of th. th.rmal, electrical, and magnetic energies.and newly defined natures.of th. electric ch.rges.and magnetic flux as.energy, or as.electromagnetic waves. th.t h.ve electric and magnetic potentials. Th. introduced diffus.on equations.of th. electric ch.rges.and magnetic flux involve Laplacian operator and th. introduced diffus.vities. Both.equations.are applied to determine th. electric and magnetic fields.in conductors.as.th. h.at diffus.on equation wh.ch.is.applied to determine th. th.rmal field in s.eady and uns.eady h.at diffus.on conditions. Th. us. of electric networks.for experimental modeling of th.rmal networks.repres.nts.s.fficient proof of s.milarity of th. diffus.on equations.of both.fields. By analys.s.of th. diffus.on ph.nomena of th. th.ee cons.dered modes.of energy trans.er;th. rates.of flow of th.s. energies.are found to be directly proportional to th. gradient of th.ir volumetric concentration, or dens.ty, and th. proportionality cons.ants.in s.ch.relations.are th. diffus.vity of each.energy. s.ch.analys.s.leads.als. to find proportionality relations.between th. potentials.of s.ch.energies.and th.ir volumetric concentrations. Validity of th. introduced diffus.on equations.is.verified by corres.ondence th.ir s.lutions.to th. meas.rement res.lts.of th. electric and magnetic fields.in microwave ovens.
