Angle of dip at pole is
- A0°
- B90°Correct
- C45°
- D30°
Solution
Concept
Angle of dip
Step-by-step solution
1. The dip is the angle between the direction of the earth’s magnetic field and the horizontal. 2. At the magnetic poles the field is vertical, so dip = 90°.
Explanation
The dip is 0° at the magnetic equator and 90° at the magnetic poles. For this reason the compass needle is balanced with a rider to counteract the dip.
Shortcut
Equator 0°, Pole 90°.
Common mistake
Choosing 0° by mixing it up with the equator.
Correct answer: B) 90°
