Abstract
An electromagnetic pressure-sensitive pointer is disclosed. The electromagnetic pointer comprises a pen core and an oscillating circuit. The pointer core has a pointer tip. The oscillating circuit comprises a plurality of conductive terminals and a conductor. A capacitance of the oscillating circuit is increased through the contact between the conductive terminals and the conductor as a force is applied upon the pointer tip. When pointer's tip is been pressed, the pointer's frequency will have an obvious transition while its pressure-sensitivity is maintained.
