Abstract: An electromagnetically controlled wheel resistance adjusting device includes a motor, a magnetic tile, a potentiometer, a circuit board, a socket, a connecting rod and an output gear. The socket, the motor and the potentiometer are electrically connected to the circuit board, respectively. An external controller may, through the socket and the circuit board, provide power to the motor and control operation of the motor. The external controller may, through the socket and the circuit board, provide power for the potentiometer and receive an output voltage sent by the potentiometer. The motor drives the magnetic tile to move through the output gear and the connecting rod. The output voltage of the potentiometer varies with the rotation angle of the output gear. The external controller may drive the magnetic tile to rotate through the motor, and determine the moving angle of the magnetic tile through the output voltage of the potentiometer.
