In the article it explains that the core of the earth has a magnetic strip which depending on its

intensity can guide animals in different directions. However a question was posed about the ability to detect such a small electric field. Since this magnet is in the core of the earth the intensity on the surface is so weak that how could an animal possible be able to use this source or cue. Well after endless experiments it is concluded that some animals that use this technique can detect electric fields as weak as five-billionths of a volt per centimeter.

Applying this new idea to the migration of sea turtles. This experiment concluded that the turtles used the magnetic field as navigational markers. These markers "guide them through the ocean, allowing the turtles to avoid fatally cold currents and stay on a path leading towards home." Because of the intensity of the magnetic f
