Part A what is magnitude of the magnetic flux through this crede due to a uniform magnetic field B-0240T that points in the +; drection? My Answers Give Up Part B magnitude of the magnetic flux through this orole due to a uniform magnetic feld B.0.240T that points at an angle of 53.8" from the what ist direction + My Answers Give Up Part C what the magntude of the magnetic flux through this crde due to a uniform magnetic field B·0.240T that points in the + y direction? My Answers Give UeExplanation / 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
