MAGNETIC FIELD INTENSITY CHANGING DEVICE AND A CHANGING METHOD THEREOF CAPABLE OF CHANGING A REFERENCE MAGNETIC FIELD INTENSITY ABOUT A REFERENCE DISTANCE TO A MAGNETIC FIELD INTENSITY ABOUT A SPECIFIC TARGET DISTANCE

摘要

PURPOSE: A magnetic field intensity changing device and a changing method thereof are provided to efficiently confirm whether a magnetic field intensity measured in a remote position from a magnetic field source satisfies a standard.;CONSTITUTION: A magnetic field intensity changing device includes an input unit (402) and a control unit (401). The input unit receives a reference distance and a target distance from a magnetic field generating source. The control unit primarily compares the reference distance with a threshold value calculated according to a wavelength of an electromagnetic wave and secondarily compares the target distance with the threshold value. The control unit changes a reference magnetic field intensity defined for the reference distance to a magnetic field intensity for the target distance based on the comparison results to calculate a changed magnetic field intensity.;COPYRIGHT KIPO 2013;[Reference numerals] (401) Control unit; (402) Input unit; (403) Memory; (404) Output unit
