摘要： A device for transmitting data includes a transmitting coil configured to receive and transmit the data signal and to generate a magnetic field, and a magnetic material provided on one surface of the transmitting coil. A ratio of a residual magnetic flux density and a saturation magnetic flux density of the magnetic material is greater in a direction that the material is magnetized than in a direction the material is not magnetized.
