The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) given in the problem. ### Step 1: Analyze the Assertion (A) The assertion states that "Every magnetic configuration has a magnetic field with a north pole and a south pole." - This statement is true. In magnetism, magnetic monopoles (isolated north or south poles) have not been observed. Every magnetic field configuration we encounter has both a north and a south pole. Therefore, the existence of both poles is a fundamental characteristic of magnetic fields. ### Step 2: Analyze the Reason (R) The reason states that "North pole and south pole exist only if the source of the field has a net magnetic dipole moment." - This statement is also true. A magnetic dipole moment is a vector quantity that represents the strength and orientation of a magnet or current loop. For a magnetic field to have distinct north and south poles, there must be a net magnetic dipole moment present. If there is no net dipole moment, the source does not exhibit magnetic behavior, and thus, no distinct poles can be identified. ### Step 3: Determine the Relationship Between A and R Now we need to evaluate the relationship between the assertion and the reason. - Both statements are true. However, the reason provided does not directly explain the assertion. The assertion speaks about the general nature of magnetic configurations while the reason specifically addresses the condition under which poles exist based on dipole moments. ### Conclusion Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct answer is that both statements are true, but the reason is not correctly explained in relation to the assertion. ### Final Answer Both A and R are true, but R does not correctly explain A. ---
