The invention provides a combined toy top with the magnetic control separating function. The combined toy top comprises a main top body, an auxiliary top body and an elastic part, and the main top body is fixed on the auxiliary top body by the auxiliary top body in a limited mode and compresses the elastic part. The combined toy top is characterized in that a magnetic control device, a motor, a power source and a connecting part are arranged in the auxiliary top body, a motor rotating shaft is in linkage with the connecting part, the main top body is fixed on the auxiliary top body in the limited mode through the connecting part, a magnetic object gets close to the magnetic control device to generate magnetic induction, then the motor is powered on to drive the connecting part to rotate so as to remove limited fixation, and the combined toy top is separated into the main top body and the auxiliary top body which rotate individually. Therefore, a player can separate the top according to own will, as the non-contact magnetic induction unlocking is adopted, rotation of the toy top is not affected, the whole game process is controllable, operability is high, the playing method is more newfangled, interestingness is high, the top is divided into the two top bodies, attack force of the top of the own side is greatly increased, the victory probability is higher, and the combined toy top can gain favor of more players.
