Explanation Magnetic anomaly refers to the differences in the strength of the magnetic field from one place to another on Earth’s surface. Magnetic anomalies may be due to differences in the circulation pattern of liquids in the core or due to differences in the types of rocks in a region. Rocks such as magnetite have a greater concentration of iron, and this is why they have greater magnetic properties. The strength of Earth’s magnetic field is measured by an instrument called the magnetometer. Magnetic anomalies at sea are called marine magnetic anomalies...

The term magnetic anomaly. Also determine the way in which magnetic anomalies are measured at sea. Introduction: Earth’s magnetic field acts a protective layer and helps to sustain life on Earth. It is produced by the motion of the liquid metal core and protects Earth from harmful radiations. The magnetic field of Earth varies across different regions.
