Motivated by the recent detection of GW170817 by the LIGO-VIRGO observatories, we study the effects of highly magnetized stars on the Love number and dimensionless tidal polarizability. We also investigate the fundamental quasinormal mode of neutron stars under such high magnetic fields. To perform our calculations we use the chaotic field approximation and consider both nucleonic and hyperonic stars. We conclude that the role played by the constitution of the stars is far more relevant than the intensity of the magnetic field and if massive stars are considered, the ones constituted by nucleons only present frequencies somewhat lower than the ones with hyperonic cores, a feature that can be used to point out the real internal structure of neutron stars. Moreover, highly magnetized stars could only be discriminated by the fundamental mode frequency in the limiting case of magnetic field intensities of the order of 3$\times 10^{18}$ G.
