AC generator calculation question

[Th3_PhYsIcS]

1. Calculate the emf induced in ONE side of a coil of length 0.4m and width 0.3m, when there are 50 turns in the coil and the flux density is 96.8 mT, and the coil is rotated 30 degrees from the vertical. Frequency is 50 Hz and the long sides are the ones facing the magnets.

2. Relevant equation(s): EMF = v l B N sinθ

3. My attempt: v = 2 ∏ (0.3/2) * 50 = 47.13 ms-1 ∴ emf = 47.13(0.4)(96.8 * 10^-3)(50)(sin30) = 45.62 V

is ^ my method correct. Sorry i am new to these forums

Can't find anything wrong, so unless the picture we have of the situation is wrong, that's the emf !
