a) $ϕ_{a b c d} = \overset{⇀}{E} \times d \overset{⇀}{A_{a b c d}}$

$ϕ_{a b c d} = (E) {(d A)}_{a b c d} \cos (180)$

$ϕ_{a b c d} = (1.50 T) (30 c m \times \frac{10^{- 2} m}{1 c m}) (40 c m \times \frac{10^{- 2} m}{1 c m}) (- 1)$

$ϕ_{a b c d} = - 0.18 w b$

b) $ϕ_{b e f c} = \overset{⇀}{E} \times d \overset{⇀}{A_{b e f c}}$

$ϕ_{b e f c} = (E) {(d A)}_{b e f c} \cos (90)$

$ϕ_{b e f c} = (1.50 T) (30 c m \times \frac{10^{- 2} m}{1 c m}) (30 c m \times \frac{10^{- 2} m}{1 c m}) (0)$

$ϕ_{b e f c} = 0$

c) $ϕ_{a e f d} = \overset{⇀}{E} \times d \overset{⇀}{A_{a e f d}}$

$ϕ_{a e f d} = (E) {(d A)}_{a e f d} \sin θ$

$ϕ_{a e f d} = (1.50 T) (30 c m \times \frac{10^{- 2} m}{1 c m}) (50 c m \times \frac{10^{- 2} m}{1 c m}) (\frac{40 c m}{50 c m})$

$ϕ_{a e f d} = 0.18 w b$
