At magnetic poles, the angle of dip is
- a.45
- b.30
- c.Zero
- d.90
Answer: (D) 90
The angle of dip (the angle a freely suspended magnetic needle makes with the horizontal) is 90° at the magnetic poles, where Earth's magnetic field lines point straight down/up into the ground; at the magnetic equator, the dip is 0° (the needle stays horizontal).
