The PZT piezoelectric ceramic on the copper alloy plate shows a extraordinary pattern resulted from the electromagnetic and thermal radiation induced by copper coil. The Eddy current or magnetic field by the polarization of PZT grains contained Pb, Zr, Ti with oxide is performed to show the change of array pattern at piezoelectric grains, especially wave-shaped or wrinkled configuration along with lines of electromagnetic field are becoming larger than before while applying the coil induction.
