<P>PROBLEM TO BE SOLVED: To generate an electromagnetic induction phenomenon by moving a coil formed by winding a carbon fiber in a magnetic field or by changing the magnetic field penetrating through the coil formed by winding the carbon fiber changes. <P>SOLUTION: A bar magnet is put in and out of the coil formed by winding a PAN-based CF or a pitch-based CF to cause the magnetic field in the coil to change and to generate an induced electromotive force, indicating that the carbon fiber made principally of carbon can substitute a copper lead wire. <P>COPYRIGHT: (C)2008,JPO&INPIT |
