We discuss Electron Cyclotron Maser Emission (ECME), observed in the form of highly circularly polarized pulses, from a few hot, magnetic stars. This emission is one of the manifestations of stellar wind-magnetic field interaction. With the Giant Metrewave Radio Telescope (GMRT), we have observed ECME from four magnetic B/A-type stars. Currently, we are trying to understand certain properties of the ECME pulses and their dependence on the magnetospheric plasma. Here, we briefly review all those works which have used ECME observed from hot magnetic stars to infer some physical properties of the host stars. We finally discuss how this phenomenon can further be exploited to probe the stellar magnetosphere.
