The “Cordless Power Station” is a power supply system without a cord. The system makes use of electromagnetic induction generated with coils. This system will have uses such as supplying power to portable household electric appliances or charging circuit systems for batteries. We studied the powertransmitting characteristics and the structure of the Cordless Power Station. We also measured the distribution of the magnetic flux density around the coils and discussed the effects of using amorphous fiber.
