Abstract
The understanding of geological processes represents a challenge for many reasons, including the appropriate handling of concepts from many sciences. This is the case of the phenomena related to Plate Tectonics such as oceanic accretion, which causes the creation of new oceanic crust and the displacement of the continents. This article presents the implementation of a simple experiment that allows visualizing and understanding the origin, generation and migration of magnetic anomalies forming parallel along of midocean ridges. The experiment is accompanied by an explanation of basic concepts such as the Earth's magnetic field, the magnetization process, thermoremanent magnetization and the structure of an oceanic ridge. Additionally, the relevance of these concepts in the Plate Tectonics development is highlighted. The material needed for the experiment is very accessible and cheap.
