PURPOSE: An unnecessary magnetic field cancellation method around an on-line electric vehicle, an apparatus using the same, and an on-line electric vehicle for cancelling an unnecessary magnetic field are provided to analyze the pattern of an unnecessary magnetic field occurring in a current collecting device and analyze the strength of a magnetic flux density, thereby properly compensating for a magnetic field of the current collecting device. CONSTITUTION: An unnecessary magnetic field cancellation method around an on-line electric vehicle comprises the following steps. An analysis unit receives a current value of a base station applied to a power supply line to supply power to an on-line electric vehicle with a current collecting device(S10). The analysis unit analyzes the pattern and the strength of an unnecessary magnetic field which does not contributes to an induced electromotive force induced into the current collecting device(S20). A coil is wound on one end or both ends of the current collecting device to maximally cancel the analyzed unnecessary magnetic field(S30).
