Explanation / Answer

here B = 5.8 x 10 -2 T d = 16 cm r = 8 cm = 0.08 m

so the area of circular loop

A = pie x r2  = 3.14 x 0.08 x 0.08 = 0.020096 m2

(a) when Q = 0o

as we know that the magnetic flux

fie = BA cosQ

flux = (5.8 x 10-2) (0.020096) cos0o

flux = 0.001165 Wb Ans

(b) when Q = 30o

flux = (5.8 x 10-2) (0.020096) cos30o

flux = 0.0010094 Wb Ans

(c) when Q = 60o

flux = (5.8 x 10-2) (0.020096) cos60o

flux = 0.0005827 Wb Ans

(d) when Q = 90o

flux = (5.8 x 10-2) (0.020096) cos90o

flux = 0 wb Ans
