The average electric field of electromagnetic waves in certain region of free space is 9 × 10-4 NC. Then, the average magnetic field in the same region is of the order of: |
27 × 10-4 T 3 × 10-12 T $\left(\frac{1}{3}\right)$ × 10-12 T 3 × 1012 T |
3 × 10-12 T |
Given, $E=9 \times 10^{-4} NC^{-1}$ We know that, $c=\frac{E}{B} \Rightarrow B=\frac{9 \times 10^{-4}}{3 \times 10^8}=3 \times 10^{-12} T$ |
