| Research Abstract |
For infinite plate metals of aluminum and titanium of which properties were known, electromagnetic experiments to heat samples by the induction, to make ones vibrated by the force and to induce the field around ones were performed by use of an alternate current of which frequency was from 10Hz to 1.0kHz. Those established as follows. In the case of low thermal diffusivity, reduced temperature observed for a sample heated by the induction agreed with the solution of equation for heat conduction. Elastic deformation of which frequency was 2 times larger than one of the alternate current was acoustically detected by a microphone. Dependence of amplitude and that of phase difference for an electric potential on frequency of alternate current agreed with that of the solution for electromagnetic equation.
