The present investigation is intended to demonstrate the magnetic field,
relaxation time, hydrostatic initial stress, and two temperatures on the
thermal shock problem. The governing equations are formulated in the
context of the Lord-Shulman theory with the presence of body force, two
temperatures, thermal shock, and hydrostatic initial stress. We obtained
the exact solution using the normal mode technique with appropriate
boundary conditions. The field quantities were calculated analytically
and displayed graphically under the thermal shock problem with the
effect of external parameters with respect to space coordinates. The
results obtained are in agreement with the previous results obtained by
others when the new parameters vanish.
