Question

True or False

When B field is parallel to a plane surface, the flux through the plane is zero. () When B field is parallel to a plane surface, the flux through the plane is a maximum. () When B field is perpendicular to a plane surface, the flux through the plane is zero. () When B field is perpendicular to a plane surface, the flux through the plane is a maximum. () For a uniform B field, that makes an angle theta with the normal direction of the surface with area A, the flux is BAcos theta () For a uniform B field, that makes an angle theta with the normal direction of the surface with area A, the flux is BA sin theta

Explanation / Answer

1) False. Because Flux = BAcos(theta) If theta = 0 flux is maximum not zero

2) True. Same reason as above

3) True. Here cos(theta) = 0

4) False

5) True. By definition of flux

6) False because correct definition of flux is= BAcos(theta)
