EM wave

[logistic_guy]

If the magnetic field in a traveling EM wave has a peak value of \(\displaystyle 17.5 \ \text{nT}\), what is the peak value of the electric field strength?

The relation between electric field and magnetic field is given by:

\(\displaystyle \frac{E_0}{B_0} = c\)

Then,

\(\displaystyle E_0 = B_0c = 299792458(17.5 \times 10^{-9}) = \textcolor{blue}{5.25 \ \text{V/m}}\)
