QPages 275-276: Q10: HC Verma: Concepts of Physics - Volume 2 Permanent Magnets Pages 275-276: Q10 Solution: Can the dip at a place be a) zero b) 90�?
⚠️ Common Exam Traps & Conceptual Pitfalls
Students often assume the magnetic dip can never be exactly 0° or 90°, confusing the definition of dip with a generic inclination; remember that dip is the angle between the Earth's magnetic field line and the horizontal plane, so at the magnetic equator the field is perfectly horizontal (dip = 0°) and at the magnetic poles it is perfectly vertical (dip = 90°).
Can the dip at a place be a) zero b) 90�?
Step-by-Step Verified Solution
**Answer:** (a) Yes, dip can be zero. (b) Yes, dip can be 90�.
**Step-by-Step Explanation:**
(a) At the magnetic equator, the magnetic field is horizontal, so the angle of dip is 0�.
(b) At the magnetic poles, the magnetic field is vertical, so the angle of dip is 90� [citation:3].
