Further, the control board 12 controls the electromagnet 11 to generate a magnetic force repelling the permanent magnet 21. Specifically, the magnetic force includes an attractive force and a repulsive force. The attraction force is the force generated by the electromagnet 11 and attracted with the permanent magnet 21; the repulsive force means a force generated by the electromagnet 11 to repel the permanent magnet 21.

Specifically, when the kettle body 2 is placed on the base 1, the magnetic induction sensor detects the magnetic field intensity generated by the permanent magnet 21 in real time and sends the detected magnetic field intensity to the control panel 12. The control panel 12 can judge the distance between the kettle body 2 and the base 1 according to the intensity of the magnetic field intensity. When the kettle body 2 generates a strong magnetic field, the control panel 12 sends a signal to the electromagnet 11 to enable the electromagnet 11 to generate a slight repulsive force, so that a user can separate the kettle body 2 from the base 1 with small practical strength. When the pot body 2 is far away from the base 1 and the magnetic induction sensor detects that the magnetic field strength is weak or the magnetic field cannot be detected, the control panel 12 sends a signal to the electromagnet 11 to generate strong attraction force, so that the pot body 2 and the base can be quickly aligned to carry out further water boiling operation.

Furthermore, when the distance between the pot body 2 and the base 1 is larger than 1cm, the control panel 12 controls the electromagnet 11 to generate magnetic force for attracting the permanent magnet 21, and when the distance between the pot body 2 and the base 1 is smaller than or equal to 1cm, the control panel 12 controls the electromagnet 11 to generate magnetic force for repelling the permanent magnet 21.

Specifically, the control board 12 may preset the attraction force generated by the electromagnet 11. For example, the attraction is generated when the kettle body 2 and the base 1 are more than 20cm apart; for another example, the repulsive force is generated when the pot body 2 and the base 1 are less than 1cm apart. In other embodiments, it may be provided that the control board 12 does not send a signal to the electromagnet 11 to generate a magnetic force.
