The MAGNEX large-acceptance ray-tracing magnetic spectrometer has recently been used with beams from the INFN-LNS Tandem accelerator. After an accurate commissioning, the instrument has started an ambitious experimental program. In the first experiment the {sup 19}F({sup 7}Li,{sup 7}Be){sup 19}O charge-exchange reaction was studied at 52 MeV incident energy. The {sup 19}O excitation energy spectrum was reconstructed and the angular distributions measured. The second experiment was aimed at the study of the {sup 15}C via the {sup 13}C({sup 18}O,{sup 16}O){sup 15}C reaction at 84 MeV incident energy. The ejectiles where detected at forward angles and mass identified by means of an innovative technique. The {sup 15}C excitation energy spectra up to about 20 MeV were obtained with a 250 keV FWHM energy resolution. In addition to several known states, the spectra show two unknown resonant-like structures at 11.4 and 14.0 MeV. The strong population of these structures, together with the measured widths, could indicate the collective nature of these states associated to a correlated neutron pair transfer. Besides the first results of physical interest from these two experiments, future experiments with MAGNEX are briefly outlined.
