Magnetic Declination

Angle of decl...

Question

Angle of declination at a place is 18 degree how can a magnetic compass be used to find the exact direction of geographical North at that place

Open in App

Solution

If it is positive declination then you turn 18^o in the anticlockwise direction to the direction shown by the compass needle to get the true geographical north.

If the declination is negative then you turn 18^oin the clockwise direction to compensate for the declination.
