MAGNETIC ANOMALY

the magnetic compass points to the magnetic north of the planet but in certain areas regional magnetic conditions can affect the accuracy of the compass. While under the influence of those areas the compass cannot be relied upon to indicate north accurately. This phenomenon is called a magnetic anomaly. An anomaly is a departure from the regular arrangement; abnormality. —Welcome to the SO Glossary Final approval 2-Mar-90
