During the hike, you found that the compass needle began to behave uneasily, showing one direction or the other. Why could this happen? What would you consider necessary to do in this case?
The compass needle is always restless in areas of magnetic anomalies. The causes of the anomalies may be due to the presence of iron ore reserves. It is necessary to mark this area on the map and, upon returning home, report this to the nearest geological department. You will have to return home according to local characteristics: stars, sun, etc.
