Question

Varying electric and magnetic fields regenerate each other. Explain.

✓

Answer

According to Maxwell’s theory, accelerated charges radiate EM waves.
Consider a charge oscillating with some frequency. This produces an oscillating electric field in space, which produces an oscillating magnetic field which in turn is a source of oscillating electric field.
Thus, varying electric and magnetic fields regenerate each other.
