  1. All numerical values are rounded off to two decimal places. ρc is the central density, M is the gravitational mass, Rcirc is the circumferential radius, re is the equatorial radius, rp/re is the ratio of polar radius rp to equatorial radius re (a purely toroidal field elongates the NS along the z-axis), \({{{{{{{\mathscr{H}}}}}}}}/{{{{{{{\mathscr{W}}}}}}}}\) is the ratio of total magnetic energy \({{{{{{{\mathscr{H}}}}}}}}\) to total binding energy \({{{{{{{\mathscr{W}}}}}}}}\), and \({B}_{\max }\) is the maximum field strength achievable inside the star. These quantities are defined according to the work from Pili et al.3. All the 12 models share the same rest mass M0 = 1.68M, polytropic constant K = 1.6 × 105 cm5 g−1 s−2, and adiabatic index γ = 2. The 11 magnetized models also share the same toroidal magnetization index m = 1.
