The magnetic meridian swings like a pendulum. It swings in one direction for a long time (100 to 200 years) and gradually comes to rest and then swings in the opposite direction.
The change produced annually by secular variation amounts in different places from 0 to 12 minutes (Period) but does not remain constant at any place.
