At a point A on the earth's surface the angle of dip, δ = + 25º. At a point B on the earth's surface the angle of dip, δ = - 25º . 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.

A is located in the northern hemisphere and B is located in the southern hemisphere.
step by step explanation:
- An angle between horizon and resultant magnetic field of earth called angle of dip.
- The value of angle of dip is zero form equator.
- Positive for Northern hemisphere and negative for Southern hemisphere.
From the given,
A on the earth's surface the angle of dip, δ = + 25º
B on the earth's surface the angle of dip, δ = - 25º
If we draw a graph for these two value as shown below.

Therefore, A is located in the northern hemisphere and B is located in the southern hemisphere.
Hence, correct option - 3
