Solution
The correct option is B False
Answer is B.
The vertical plane passing through the axis of a freely suspended magnet is called magnetic meridian. The direction of Earth's magnetic field lies in the magnetic meridian and may not be horizontal. The vertical plane passing through the true geographical North and South (or geographical axis of Earth) is called geographical meridian. The angle between the magnetic meridian and the geographic meridian at a place is called declination at that place.
The value of the angle of declination is different at different places on Earth. To find the exact geographic directions (North and South) at a place by using a magnetic compass, we should know the angle of declination at that place. The declination is expressed in degrees East or degrees West.
