Question
In an electromagnetic wave, the electric magnetising fields are $\frac{100\text{V}}{\text{m}}$ and $\frac{0.265\text{A}}{\text{m}}$ The maximum energy flow is?
✓

Answer

Maximum rate of energy flow, $S = E_0 ​\times H_0$
Given, $\text{E}_0=\frac{100\text{V}}{\text{m}},\text{H}_0=\frac{0.265\text{A}}{\text{m}}$
$\therefore\text{S}=100\times0.265=\frac{26.5\text{W}}{\text{m}^2}$​
