An electromagnetic sensing apparatus is provided for a touch screen having a display and a soft key. The electromagnetic sensing apparatus includes a Printed Circuit Board (PCB) including a display area corresponding to the display and a sub-area corresponding to the soft key, a controller including channels , which controls electromagnetic sensing of the electromagnetic sensing apparatus, and a plurality of loop units that extend from the channels and output current induced by an electromagnetic field. At least one of the plurality of loop units includes a first sub-loop arranged in the display area and a second sub-loop arranged in the sub-area. At least one of the plurality of loop units includes a first sub-loop arranged in the display area and does not include a second sub-loop.
