Electromagnetic field

An electromagnetic field is a field that is created by electrical equipment, like a holoprojector. As demonstrated by a B1 during the Onderonian Civil War, B1-series battle droids had the capacity to detect these fields. A droid detected an electromagnetic field originating from an imagecaster, and another droid identified its source. This battle droid then proceeded to investigate the bag, while his two accompanying units retreated in fear; however, a message from Onderon's past king, Ramsis Dendup, commenced playing, in which Dendup implored the Onderonian population to resist the Confederacy of Independent Systems. The civilian followed his advice, and the three battle droids that had found the field were quickly eliminated. Tensor fields represent one particular kind of electromagnetic field.
