Question

B a a A square wire frame with an edge of a = 3 (m) was placed in a uniform B = 3i (1) magnetic field. The wire frame is rotated around the axis connecting the diagonals with a constant angular velocity 0 - 3 (rad/s). The angle 8 between the frame plane and the magnetic field is zero at 1-0. What is the maximum value of the electromotive force induced in the frame? A-) 12 8-) 81 0 0 0 0 C-) 36 D-) 24 E-) 54 o

Answer 1

if u have any doubt u can ask me in comment box.....hope u like it....

B = 3 a = 3(m) Area A=a2 A=9 m2 - BA caso w=do 3 rad/s dt emf = (do a d (BAQ) dt x -|-60 -BA sino do dt max value of sino 1 sinomax - 3x9x sino x x 3 3 x 9 x 1 x3 emf 81 V option (B) 81 is correct
