Magnetism and Matter - Result Question 8
12. 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:
[2019]
(a) $A$ and $B$ are both located in the northern hemisphere.
(b) A is located in the southern hemisphere and $B$ is located in the northern hemisphere.
(c) A is located in the northern hemisphere and $B$ is located in the southern hemisphere.
(d) A and B are both located in the southern hemisphere.

Answer:
Correct Answer: 12. (c)
Solution:
- (c) As we know that the angle of dip is the angle between earth’s resultant magnetic field from horizontal.
At equator, dip is zero. At Northern hemisphere, dip is positive. At southern hemisphere, dip is negative.
