Loggerhead turtles sense latitude by the planet's magneticfieldintensity, and new research finds they're good at determining their longitude too, probably via the field's inclination.
Maxwell's equations conserve certain properties-the magneticfieldintensity, the electric displacement field and the Poynting vector that describes the electric flux of an electromagnetic field.

Changing of material resistance with applied magneticfieldintensity is called Giant magnetoresistance (GMR).
