At a point \(A\) on the earth's surface the angle of dip, \(\delta=+25^{\circ}\). At a point \(B\) on the earth's surface the angle of dip, \(\delta=-25^{\circ}\). We can interpret that:
1 \(A\) and \(B\) are both located in the northern hemisphere.
2 \(A\) is located in the southern hemisphere and \(B\) is located in the northern hemisphere.
3 \(A\) is located in the northern hemisphere and \(B\) is located in the southern hemisphere.
4 \(A\) and \(B\) are both located in the southern hemisphere.
Explanation:
The dip is positive if the north pole of the magnetic needle faces downward, negative if it faces upward. As the needle faces down at the geographic north pole. So the correct option is (3).

Assertion : A dip circle (used for dip measurement) is taken to geomagnetic equator. The needle is allowed to move in a vertical plane. The needle will stay in any direction when it is released. Reason : At geomagnetic equator \(B_{v}=0\).
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
