Since It possesses the force fields(electric and magnetic), It should be either attracted or repelled to an external force field. But It does do nothing in reality. Why?How?
Because electromagnetic force fields exert forces on electrical charges, not on other force fields. Electromagnetic waves are charge-free.

I forgot to mention that the external field of force is either an electric or a magnetic field.

I thought that you meant electric or magnetic fields.
If you send a beam of electrons through the electric field between the deflection plates of a cathode ray tube (used in the good old days in oscilloscopes) or through the magnetic field of the deflection coils (as used in ancient TV sets), then the electron beam is deflected according to the Lorentz force:
F = q * (E + v x B)
If you would send a beam of light (diameter considerably smaller than the clear width of the plates or the coils) through these fields, then q (the charge of the beam) would be zero, and so would be the force on the beam.
It's quite a different story if the beam propagates through matter (Faraday effect, Kerr effect etc.) because matter includes charged particles.
Electromagnetic fields can interact with each other non-linearly, but that is a high-energy effect. https://www.aanda.org/articles/aa/full/2003/09/aaek205/aaek205.right.html
They also attract each other by gravity because they contain energy.
