Claim 7:
8. A smart kettle used over a smart table configured to generate a magnetic field, the smart kettle comprising:
a body that is configured to increase in temperature in response to the magnetic field generated by the smart table; and
a controller that is configured to output a control signal to adjust a strength of the magnetic field based on the temperature of the body,
wherein the controller is configured to output the control signal to adjust the strength of the magnetic field by:
compensating a temperature measured in the body by using pre-stored data to correct a temperature measurement error resulting from a vacuum space between an inner surface of a bottom of the body and an outer surface of a bottom of the body, and
adjusting the strength of the magnetic field based on the temperature measured in the body.
