Abstract: Disclosed herein is a laundry machine. More particularly, a laundry machine for generating steam by an induction heater and a control method thereof are disclosed. According to an embodiment of the present disclosure, provided is a method of controlling a laundry machine including a tub, a drum rotatably arranged in the tub to accommodate an object and provided with a through hole on an outer circumferential surface thereof, and an induction heater provided to the tub, and configured to perform a steam operation. The steam operation may include heating a heating surface of the drum facing the induction heater by driving the induction heater, spraying, through a spray nozzle, water toward the heating surface heated in the heating operation, and rotating the drum such that the steam is introduced into the drum through the through hole in a space between the tub and the drum.
