Question

The resultant magnetic flux generated in the closed surface will be

• A. Zero
• B. Continuous
• C. Constant
• D. Unity

Hint:

Gauss’s Law for magnetism states that the total magnetic flux through a closed surface is always zero because there are no magnetic monopoles.

Answer 1

The Correct Option is A

Step 1: According to Gauss’s Law for magnetism: \[ \oint_S \mathbf{B} \cdot d\mathbf{A} = 0 \] where \( \mathbf{B} \) is the magnetic field and \( d\mathbf{A} \) is the infinitesimal area element over a closed surface. 
Step 2: This law states that the net magnetic flux through a closed surface is always zero because magnetic monopoles do not exist; instead, magnetic field lines always form closed loops. 
Step 3: Since every magnetic field line that enters a closed surface must exit, the total inward and outward flux cancel each other out, leading to a net flux of zero.
