Explain the terms
`(i)` magnetic declination
`(ii)` angle of dip at a given place.

Explanation

To explain the terms "magnetic declination" and "angle of dip" at a given place, we can break down the concepts step by step.

### Step 1: Define Magnetic Declination
Magnetic declination is the angle between the magnetic meridian (the direction of the magnetic field) and the geographic meridian (the direction of true north) at a specific location on Earth.

### Step 2: Explain the Importance of Magnetic Declination
Magnetic declination varies from place to place and changes over time. It is important for navigation, as compasses point towards the magnetic north, which may not align with true north due to this declination.
