The Neutron Star (NS) Interior Composition ExploreR (NICER) has been operating aboard the International Space Station since 2017. Its ultimate aim is to constrain the equation of state of NSs with better precision. Recent studies have strongly indicated the presence of a multipolar magnetic field in the millisecond pulsars (MSPs) observed by NICER. We have implemented a complete, fully-analytical, and generic multipolar magnetic field up to an octupole component to (i) model their thermal X-ray light curves, (ii) predict the morphology of surface emission hotspots, and (iii) constrain their mass and radii. In my talk, I will discuss the magnetic field equations, highlight the field configuration for different components, and present preliminary results for an MSP (PSR J0030+0451).
