  Recently super-Chandrasekhar mass limit has been derived theoretically in
presence of strong magnetic field to complement experimental observations. In
the framework of Newtonian physics, we have studied the equilibrium
configurations of such magnetized white dwarfs by using the relativistic
Thomas-Fermi equation of state for magnetized white-dwarfs. Hartle formalism,
for slowly rotating stars, has been employed to obtain the equations of
equilibrium. Various physical quantities of uniformly rotating and non-rotating
white dwarfs have been calculated within this formalism. Consequently, the
universality relationship between the moment of inertia(I), rotational love
number($\lambda$) and spin induced quadrupole moment(Q), namely the I-Love-Q
relationship, has been investigated for such magnetized white dwarfs. The
relationship between I, eccentricity and Q i.e. I-eccentricity-Q relationship
has also been derived. Further, we have found that, the I-eccentricity-Q
relationship is more universal in comparison to I-Love-Q relationship.
