हिन्दीA big circular coil of \( 1000\text{ turns} \) and average radius \( 10\text{ m} \) is rotating about its horizontal diameter at \( 2\text{ rad s}^{-1} \). If the vertical component of earth's magnetic field at that place is \( 2 \times 10^{-5}\text{ T} \) and electrical resistance of the coil is \( 12.56\text{ }\Omega \), then the maximum induced current in the coil will be:
Correct answer · Option 1
\( 1\text{ A} \)
Explanation
\( I_{\max} = \frac{e_{\max}}{R} = \frac{N B \omega A}{R} = \frac{1000 \times (2 \times 10^{-5}) \times 2 \times (\pi \times 10^2)}{12.56} = 1\text{ A} \).
