NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyAssertion (A): | Gauss's law for magnetism states that the net magnetic flux through any closed surface is zero. |
Reason (R): | The magnetic monopoles do not exist. North and South poles occur in pairs, allowing vanishing net magnetic flux through the surface. |
