Query: Strange matter and its stability in presence of magnetic field   We study the effect of a magnetic field on the interacting quark matter and
apply to strange star. We considere the low temperature approximation to
strange matter. We find that the interacting strange quark matter is more
stable compare to free quark gas in presence of strong external magnetic field
with zero and finite temperature. We then calculate strange star structure
parameters such as mass and radius and find that the strange star is more
compact for interacting quark matter than free quark matter in presence of
strong magnetic field.
