Abstract
An apparatus for determining a type of an electromagnetic wave generating source, including: a measurement unit that measures electromagnetic field strength at first and second measurement points at vertically different respective distances from a main surface of an object to be measured; a calculation unit that calculates an attenuation amount of the electromagnetic field strength between the first and second measurement points using measured values of the electromagnetic field strength measured by the measurement unit; and a determination unit that determines whether the generating source is the electric current source or the magnetic current source by judging which one of a reference value of an electric current source and a reference value of a magnetic current source is close to a value of the attenuation amount calculated by the calculation unit.
