A) \[nBA\omega \]
B) \[\frac{3}{2}nBA\omega \]
C) \[3nBA\omega \]
D) \[\frac{1}{2}nBA\omega \]
Correct Answer: A
Solution :
| [a] Given, a coil of N turns an area A, rotated with angular speed\[\omega \] in a uniform magnetic field B. |
| The flux linking to the coil, sin\[\phi =NBA\sin (\omega t)\] |
| Therefore, |
| Induced \[E=d(NBA\sin (\omega t)/dt)\] |
| E= NBA |
| Emax= NBA |
