The electromagnetic whiteboard pen has a marker for writing with ink and a coil for emitting electromagnetic signals. When user writes on an electromagnetic whiteboard by the marker, the coil emitting electromagnetic signals simultaneously. The electromagnetic whiteboard senses the electromagnetic signals to find and record the position and the moving of the electromagnetic whiteboard pen. Therefore, the writing on the electromagnetic whiteboard by inking can be record and converted to be digital signals for storing by the electromagnetic whiteboard when the electromagnetic whiteboard pen writes on the electromagnetic whiteboard.
