In a magnetic field, diamagnetic materials are weakly magnetized in the opposite direction of the applied field. Examples of diamagnetic materials include gold, quartz, water, copper, and air. Paramagnetism : In a paramagnetic material , there are unpaired electrons. The unpaired electrons are free to align their magnetic moments. In a magnetic field, the magnetic moments align and are magnetized in the direction of the applied field, reinforcing it.
Examples of paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. Ferromagnetism : Ferromagnetic materials can form permanent magnets and are attracted to magnets. A ferromagnet has unpaired electrons, plus the magnetic moments of the electrons tend to remain aligned even when removed from a magnetic field. Antiferromagnetism : In contrast to ferromagnets, the intrinsic magnetic moments of valence electrons in an antiferromagnet point in opposite directions anti-parallel.
The result is no net magnetic moment or magnetic field. Antiferromagnetism is seen in transition metal compounds, such as hematite, iron manganese, and nickel oxide. Ferrimagnetism : Like ferromagnets, ferrimagnets retain magnetization when removed from a magnetic field but neighboring pairs of electron spins point in opposite directions. This article is about objects and devices that produce magnetic fields.

The earth is constructed with a North and South Pole and a Inner core made up of metallic composites presumably and largely iron. The Magnetic field around the earth is driven largely by this source of electromagnetism.
