PROBLEM TO BE SOLVED: To avoid inconvenience resulting from residual magnetism by demagnetizing magnetization generated during power feeding.SOLUTION: The electronic apparatus (charging platforms 4-1, 4-2, electronic apparatuses 6-1, 6-2) has a non-contact power feeding function including coils (12, 22) and includes current supply sections (14, 24). The coil generates a magnetic field (M1) with an energization current or generates a current by receiving a magnetic field. The current supply section supplies, after non-contact power feeding, a current running in the opposite direction to a current running through the coil during non-contact power feeding to the coil and generates a magnetic field (M2) with reverse polarity to a magnetic field generated during non-contact power feeding. The electronic apparatus demagnetizes magnetization generated by non-contact power feeding. |
