Answer:

length of one side of the coil is 0.1083 m

Explanation:

given data

no of turn = 269

coil rotates = 113 rad/s

magnetic field = 0.222-T

peak output = 79.2 V

solution

we will apply here formula for maximum emf induced in a coil that is

εo = N × A × B × ω ........................1

and here Area A = l²

so

l = $\sqrt{A}$

put here value of A from equation 1

I = $\sqrt{\frac{\epsilon _o}{N\times B\times \omega} }$

put here value and we will get

l = $\sqrt{\frac{79.2}{269\times 0.222\times 113}}$

l = 0.1083 m
