Question

\( \nabla \cdot \vec{B} = 0 \), shows that

• A. Electrostatic fields have no sources or sinks
• B. Magnetostatic fields have no sources or sinks
• C. Electrostatic fields have two sources and two sinks
• D. Magnetostatic fields have two sources and one sink

Hint:

Magnetic field lines have no start or end — unlike electric field lines.

Answer 1

The Correct Option is B

From Maxwell’s equations: \[ \nabla \cdot \vec{B} = 0 \] This implies there are no magnetic monopoles — magnetic field lines are always closed loops and do not begin or end at a point.
