AGN feedback in cosmic structure formation is considered a very important process. One formof carrying supermassive black hole energy is through powerful radio jets and lobes, but the physics ofjet+lobe formation is not well understood. Observations of jets+lobes inside ICM, however, are providingimportant clues in understanding the physics of such sources and help to quantify such feedback. We willpresent 3-D MHD studies of such sources and compare them with observations.
