Given below are two statements:
 Assertion (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.

 1 (A) is true but (R) is false. 2 (A) is false but (R) is true. 3 Both (A) and (R) are true and (R) is the correct explanation of (A). 4 Both (A) and (R) are true but (R) is not the correct explanation of (A).  Subtopic:  Analogy between Electrostatics & Magnetostatics |

Select correct option based on the statements:

 Statement-I: The magnetic field of a circular loop at very far away point on the axial line varies with distance as like that of a magnetic dipole. Statement-II: The magnetic field due to magnetic dipole varies inversely with the square of the distance from the centre on the axial line.

 1 Statement-I is correct and Statement-II is incorrect. 2 Statement-I is incorrect and Statement- II is correct. 3 Both Statement-I and Statement-II are correct. 4 Both Statement-I and Statement-II are incorrect.  Subtopic:  Analogy between Electrostatics & Magnetostatics |
