Abstract
An electromagnetic remote control and control method thereof; when rotating a second rotary disc (20), the repulsive force between a first magnetic piece (30) on the second rotary disc (20) and a second magnetic piece (40) on a first rotary disc (10) is increased; when detecting increase in force on the second magnetic piece (40), transmitting a corresponding control instruction to a controlled device. The controlled terminal can be controlled by rotating the second rotary disc (20) without providing additional function keys, thus the electromagnetic remote control is small and easy to carry.
