Magnetic flux through a surface is:
AB × A only
BB · A (vector dot product, B × area projected)
CB + A
DB / A
Answer & Solution
Correct answer: B. B · A (vector dot product, B × area projected)
Φ_B = ∫ B · dA = BA cos theta for uniform field, where theta is angle between B and surface normal. SI unit: weber (Wb) = T m².
