# Problem: A microwave oven operates at 2.4 GHz with an intensity inside the oven of 2350 W/m2.a. What is the amplitude of the oscillating magnetic field?b. What is the amplitude of the oscillating electric field?

###### FREE Expert Solution

The amplitude of oscillating magnetic field:

$\overline{){{\mathbf{B}}}_{{\mathbf{0}}}{\mathbf{=}}\sqrt{\frac{\mathbf{2}{\mathbf{\mu }}_{\mathbf{0}}\mathbf{I}}{\mathbf{c}}}}$, where μ0 is the permeability of free space, I is the intensity of the electromagnetic wave, and c is the speed of light in a vacuum.

The amplitude of the oscillating electric field is:

$\overline{){{\mathbf{E}}}_{{\mathbf{0}}}{\mathbf{=}}{\mathbf{c}}{{\mathbf{B}}}_{{\mathbf{0}}}}$
