What should I do if the compass is not used for a long time?

Place the magnetic needle in the north pole position. .

When the compass is not used for a long time, the magnetic needle should be placed in the north position. This is because the magnetic needle of the compass will be affected by the surrounding magnetic field, and the magnetization will shift after a long storage time. Pointing the pointer to the north can reduce the possibility of magnetization deviation. Compass can also be stored away from the interference of magnetic field to maintain its accuracy.
