Question

Find the magnetic declination if the magnetic bearing of the sun at noon is $356^\circ$.

• A. $4^\circ\text{N}$
• B. $4^\circ\text{S}$
• C. $4^\circ\text{E}$
• D. $4^\circ\text{W}$

Hint:

Magnetic declination is positive for easterly direction and negative for westerly direc tion. Always compare magnetic and true bearings carefully

Answer 1

The Correct Option is C

At noon, the true bearing of the sun is $0^\circ$. The difference between the magnetic bearing and the true bearing gives the magnetic declination: \[ \text{Magnetic Declination} = 0 - 356 = +4. \] A positive declination indicates an easterly direction, so the magnetic declination is $4^\circ\text{E}$.
