Question

what magnetic flux penetrates the flat surface 50. when the field is induced 0.4 t, if this surface: a) is perpendicular to the vector and the field's field; b) is located at an angle of 45 ° to the induction vector; c) is located at an angle of 30 ° to the induction vector

Answer 1

a)

$$\Phi=BS \sin{90}= (0.4)(50)\sin{90}=20\ Wb$$

b)

$$\Phi=BS \sin{45}= (0.4)(50)\sin{45}=14.1\ Wb$$

c)

$$\Phi=BS \sin{30}= (0.4)(50)\sin{30}=10\ Wb$$
