Question

A ceiling fan having 3 blades of length 80 cm each is rotating with an angular velocity of 1200 rpm. The magnetic field of earth in that region is 0.5G and angle of dip is 30^ . The emf induced across the blades is Nπ 10^-5V. The value of N is____

Accepted Answer

Correct answer: 32. (32) B_v= Bsin ⁡30= 14 10^-4 =2 f= 2 60 1200 rad/s = 12B_V l^2 =32 10^-5 V
