Electromagnetic waves have an electric and
magnetic field. There is an intimate relationship
between these two fields and in this present work we
adopt the theory that subatomic particles, here being
considered neutrinos, can carry the thermal energy
calculated through intrinsic kinetic energy. The field of
neutrinos determined here may be responsible for the
formation of the second harmonic, recently discovered,
in which highly energetic electromagnetic waves, in the
order of terahertz, excite superconducting electrons.
Theories related to the electron and the electric and
magnetic fields were also addressed, as their nature is
fundamental to the understanding of electromagnetic
waves, the interaction between them and the broad
effects on nature.
