Abstract

A magnetic field generator may include a magnetic field generation part including a resonance part including an inductor and a capacitor connected with each other, and which is structured so that an AC current is flowed between the inductor and the capacitor by charging electric charge to the capacitor and discharging the electric charge to generate a magnetic field by a resonance; a current direction monitoring section structured to monitor a direction of a current flowing through the inductor of the magnetic field generation part; and a judging section structured to control a timing for charging in the magnetic field generation part depending on the direction of the current flowing through the inductor which is obtained by monitoring of the current direction monitoring section.
