<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus, capable of appropriately notifying an electronic equipment user of information for correcting a displacement of a power receiving coil on the electronic equipment side from an optimum position relative to a power transmission coil on the charger side, and to provide a charging system. <P>SOLUTION: The electronic apparatus, for example a cellular phone 11, includes: a secondary coil 13 obtained by winding a conductor around a principal point 19; position-detecting coils 14 to 16 that detect the respective first, second, and third magnetic flux densities at first, second, and third points; and a notification unit 17. A first point relative to the principal point 19 is taken as a first unit vector, a second point relative to the principal point 19 is taken as a second unit vector, and a third point relative to the principal point 19 is taken as a third unit vector. The notification unit 17 provides information concerning the direction and length of movement to be made, based on the direction and the magnitude of a vector which is determined by a relation: (first magnetic flux density)×(first unit vector)+(second magnetic flux density)×(second unit vector)+(third magnetic flux density)×(third unit vector). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
