PROBLEM TO BE SOLVED: To attain convenient and inexpensive installation anywhere, by using a power induction device which permits a transformer to convert a magnetic field into electric power and then, to direct current for storing the electric power and permits a converter to output required power. SOLUTION: A magnetic field generated around a wire 6 is converted into electric power by a transformer 1. The power converted by the transformer 1 is converted into direct current in a rectifier 2 to be stored in a power storage device 3. A DC/DC converter 4 converts the power stored in the power storage device 3 into required voltage as necessary to output it into an electric apparatus or an electronic apparatus 5. For example, in the case that the power storage device 3 is formed by parallel-connecting 140 electrical double layered capacitors of maximum working voltage 5.5 V and electrostatic capacity 4.7 F, 600 mW of charged power with 10Ωof load resistance can be supplied with four-hour charging, so that a 1 W electronic apparatus can repeat its operation cycle for 60 minutes. It is thus possible to attain convenient and inexpensive installation anywhere.
