A flat, square surface with side length 4.35 cm is in the xy-plane at z=0.

Calculate the magnitude of the flux through this surface produced by a magnetic field
Bāƒ— = (0.200T)i^ + (0.250T)j^ + (0.550T)k^ .

The textbook isn't being helpful, I'll appreciate a good explanation!

Answer:

I X j = k Ā  Ā  Ā  (perpendicular to plane)

j X k = 0

i X k = 0 Ā  Ā  Ā  cross products for vectors i, j, k Ā 

Flux = B dot A Ā  Ā and only B in the k direction is relevant

Flux = .550 T * .0435^2 Ā m^2 = .00104 Webers-m^2
