Abstract: A magnetic ring and a magnetic-ring-based system are provided. The magnetic ring includes an inner magnetic ring including an inner coil and an outer magnetic ring corresponding to the inner magnetic ring and including an outer coil facing the inner coil along a circumference of the outer magnetic ring. The inner magnetic ring is connected with a stationary part in a range-finding system, and the outer magnetic ring is connected with a rotating part in the range-finding system. In response to a rotation of the rotating part with respect to the stationary part, the outer magnetic ring rotates with respect to the inner magnetic ring to generate a magnetic field between the inner coil and the outer coil to perform one of data transmission or power transmission in the range-finding system.
