Question

Which of the following choices concerning the net magnetic flux through any enclosed surface is true according to Gauss' law for magnetic fields? Select one: a. The net magnetic flux in this case would be a vector quantity equal to the enclosed magnetic field. b. The net magnetic flux in this case would be a positive scalar quantity c. The net magnetic flux in this case would be a vector quantity equal to the number of magnetic monopoles passing through the surface per unit time. d. The net Magnetic flux in this case would be a negative scalar quantity. e. The net magnetic flux in this case would be equal to zero.

Answer 1

e. The net magnetic flux in this case would be equal to zero.

Step-by-step explanation:

As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop

here we know that net magnetic flux is the scalar product of magnetic field vector and area vector

so here we have

`\int B. dA` = net magnetic flux

since we know that magnetic field always forms closed loop so if we find the integral over a closed loop

then in that case the value of the close integral must be zero

so correct answer would be

e. The net magnetic flux in this case would be equal to zero.
