Question

The rate of change of magnetic flux density through a circular coil of area 10 m and number of turns 100 is 10${}^3$ Wb/m${}^2$/s. The value of induced emf will be

• A. 10${}^{-2}$ V
• B. 10${}^{-3}$ V
• C. 10 V
• D. 10${}^6$ V

Answer 1

The correct option is D 10${}^6$ V

$emf=$ rate of change of flux

$=$ area $\times$ number of turns $\times$ rate of change of flux density
$=10\times 100\times 1000={10}^{6}V$
