  A generalized magnetothermoelasticity, in the context of Lord-Shulman theory,
is employed to investigate the interaction of a homogeneous and isotropic
perfect conducting half space with rotation. The Laplace transform for time
variable is used to formulate a vector-matrix differential equation which is
then solved by eigenvalue method. The continuous solution of displacement
component while the discontinuous solutions of stress components, temperature
distribution, induced magnetic and electric field have been analyzed in an
approximate manner using assymptotic expansion for small time. The graphical
representations also prove this continuity and discontinuity of the solutions.
