Abstract: An electromagnetic touch device and an electromagnetic touch screen are provided. The electromagnetic touch device includes the electromagnetic touch screen. The electromagnetic touch screen is coupled with a stylus. The electromagnetic touch screen includes transmitting coils and receiving coils. The transmitting coils are correspondingly arranged in a peripheral area around the receiving coils. During interaction between the stylus and the electromagnetic touch screen, the transmitting coils transmit transmitting signals to generate a first magnetic field through which the stylus is charged. When a touch operation is performed, the receiving coils generate receiving signals according to a second magnetic field generated by the stylus, a touch point of the stylus is obtained according to the receiving signals.
