Default Electric & Magnetic Fields

Maxwell's third equation( Del x E = -d/dt(B) ) saying that a changing
magnetic field induces an electric field(Faraday's Law) is
well illustrated by the working of a electric transformer or dynamo..

Similarly is there any example for the fourth equation of Maxwell (Del
x H = d/dt(D) ; Assume J=0) that a changing electric field can induce
a magnetic field ?( Except for the concept of EM waves )


Coments Please
