There are provided electromagnetic wave source detecting apparatus and method as well as electro-magnetic wave source analyzing system and method which can detect and analyze a source of (electromagnetic disturbing wave) representing a main factor in generating an electromagnetic field remotely of the apparatus in order to suppress the electromagnetic field intensity at the remote distance from the apparatus to below a regulated value. In the present invention, a magnetic field near an object 110 to be measured is measured by a set of at least two or more probes 101 and 102, a position of an electromagnetic wave source is detected through simplified calculation of one function using a phase difference between the two probes, a current distribution on the measured object is determined by solving simultaneous equations containing the position information and magnitudes of measured magnetic fields and an electromagnetic field at a remote distance from the apparatus is determined from the current distribution, thereby identifying the source representing the main factor in generating the electromagnetic field remotely of the apparatus.
