  The effect of strong magnetic field on the stability and gross properties of
bulk as well as quasi-bulk quark matter has been investigated using the
conventional MIT bag model. Both the Landau diamagnetism and the paramagnetism
of quark matter has been studied. How the quark hadron phase transition is
affected by the presence of strong magnetic field has also been investigated.
The equation of state of strange quark matter changes significantly in strong
magnetic field. It is also shown that the thermal nucleation of quark bubbles
in compact metastable state of neutron matter is completely forbidden in
presence of strong magnetic field.
