Possibility of Magnetic Mass Detection by the Next Generation of Microlensing Experiments

We study the possibility of magnetic mass detection by the gravitational microlensing technique. Recently the theoretical effect of magnetic mass on the microlensing light curve in the NUT space have been obtained and no signature of NUT factor in the microlensing candidates of the MACHO experiment have been found. In order to increase the sensitivity of detection, we propose a systematic search of the microlensing events, using the currently running alert systems and complementary photometric telescopes. In this strategy of observation, we obtain the magnetic mass detection efficiency and also an upper limit for the NUT factor that can be observed. This method of monitoring gravitational microlensing events can also be used as a tool for searching other exotic space-times.
