A generator with a circular coil of 100 turns of area $2 \times 10^{-2} m^{2}$  is immersed in a 0.01 T magnetic field and rotated at a frequency  of 50 Hz  . The maximum emf which is produced during  a cycle is 

Answer:

Explanation:

Given ,

Number of turns in circular coil=100

 Area (A)= $2 \times 10^{-2} m^{2}$

 Magnetic field (B)=0.01 T

 Frequency  of rotation (f)= 50 Hz

 We know that,

  $e= NBA \omega=NBA(2 \pi f)$

  = $100 \times 0.01 \times 2 \times 10^{-2} \times \frac{22}{7} \times 50$

 = 6.28 V
