1. A laundry treatment apparatus comprising:
a tub;
a drum disposed in the tub and configured to rotate about a rotation axis, the drum being made of metal and configured to accommodate laundry therein;
an induction module disposed at a first position of the tub and configured to heat the drum via induction using a magnetic field that is generated based on current being applied to a coil in the induction module;
at least one lifter disposed on the drum;
at least one magnet disposed at a position for determining a relative position of the at least one lifter with respect to the induction module;
a sensor disposed at a second position of the tub opposite to the first position with respect to the rotation axis of the drum, the sensor being configured to sense a position of the at least one lifter by sensing the position of the at least one magnet to thereby determine the relative position of the at least one lifter with respect to the induction module; and
at least one controller configured to control the induction module based on the relative position of the at least one lifter with respect to the induction module.
