  We study the dipolar magnetic field configuration in dependence on brane
tension and present solutions of Maxwell equations in the internal and external
background spacetime of a magnetized spherical star in a Randall-Sundrum II
type braneworld. The star is modelled as sphere consisting of perfect highly
magnetized fluid with infinite conductivity and frozen-in dipolar magnetic
field. With respect to solutions for magnetic fields found in the Schwarzschild
spacetime brane tension introduces enhancing corrections both to the interior
and the exterior magnetic field. These corrections could be relevant for the
magnetic fields of magnetized compact objects as pulsars and magnetars and may
provide the observational evidence for the brane tension through the
modification of formula for magneto-dipolar emission which gives amplification
of electromagnetic energy loss up to few orders depending on the value of the
brane tension.
