My Answers Give Ue

Explanation / Answer

Radius = R = 6.6 cm = 0.066 m

Area = A = pi R^2

B = 0.24 T

a) When B is in + z direction , theta = 0

Flux = A x B x cos(theta) = pi R^2 x B x cos(theta) = pi x 0.066^2 x 0.24 x cos(0) = 0.00328 Wb

b) When B is in 53.8 degrees with z ,

theta = 53.8 degrees

Flux = A x B x cos(theta) =  pi R^2 x B x cos(theta) = pi x 0.066^2 x 0.24 x cos(53.8 degrees) = 0.00194 Wb

c) When B is 90 degrees with + z

theta = 90 degrees

Flux = A x B x cos(theta) =  pi R^2 x B x cos(theta) = pi x 0.066^2 x 0.24 x cos(90 degrees) = 0 Wb
