  Using the framework of higher-form global symmetries, we examine the regime
of validity of force-free electrodynamics by evaluating the lifetime of the
electric field operator, which is non-conserved due to screening effects. We
focus on a holographic model which has the same global symmetry as that of low
energy plasma and obtain the lifetime of (non-conserved) electric flux in a
strong magnetic field regime. The lifetime is inversely correlated to the
magnetic field strength and thus suppressed in the strong field regime.
