## Abstract

A cookware and geometrically patterned magnetic stirrer assembly provides cookware for heating and stirring food. A heating element heats a cooking surface on the cookware. At least one geometrically patterned electromagnetic coil is integrated into the cookware. The electromagnetic coil generates a magnetic field when an electrical current passes through. At least one magnetic stirrer operates on the cooking surface to stir the food in response to the magnetic field, in accordance to the path of geometric pattern. Controllably applying varying electrical currents through the electromagnetic coil moves the magnetic stirrer in the path of the geometric pattern at varying speeds and directions. The electromagnetic coil can be arranged in a snowflake pattern, a spider web pattern, or a helix. A controller regulates electrical current through the heating element and the electromagnetic coil to allow the heating and stirring functions to operate independently of each other.
