The Earth’s magnetic north is currently[2] located in the geographical south, and its magnetic south is located in the geographical north. The mechanism is not necessarily all similar, and there are three proposals on how it works:The use of magnetic minerals such as magnetite crystals, which respond to the earth’s magnetic field. The magnetic field is odd, because its declination (angle between geographic and magnetic meridians varies across the earth’s surface. There is also magnetic inclination (dip), which is the angle of the magnetic field in relation to the horizontal at the specific location. Humans—like other animals—may sense Earth’s magnetic field.
