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.

Electromagnetism is one of the most common sources of power on the earth. 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.

8 Replies to “Magnetism”

  1. Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. This motion can take many forms. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of .
  2. Jan 21,  · Magnetism is the force exerted by magnet s when they attract or repel each other. Magnetism is caused by the motion of electric charge s. Every substance is made up of tiny units called atoms. Each atom has electron s, particle s that carry electric charges.
  3. Magnetism definition is - a class of physical phenomena that include the attraction for iron observed in lodestone and a magnet, are inseparably associated with moving electricity, are exhibited by both magnets and electric currents, and are characterized by fields of force. How to use magnetism in a sentence.
  4. Magnetism is intimately linked with electricity, in that a magnetic field is established whenever electric charges are in motion, as in the flow of electrons in a wire, or the movement of electrons around an atomic nucleus.
  5. Nov 06,  · Magnetism is defined as an attractive and repulsive phenomenon produced by a moving electric charge. The affected region around a moving charge consists of both an electric field and a magnetic field. The most familiar example of magnetism is a bar magnet, which is attracted to a magnetic field and can attract or repel other magnets.
  6. What is Magnetism? Magnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will because a magnet too. It has become magnetized.
  7. Oct 25,  · Magnetism and electricity: the theory of electromagnetism Electromagnets show that you can make magnetism using electricity. In fact, as European scientists discovered in the 19th century, electricity always makes magnetism when it moves about or changes. Every time an electric current flows in a wire, it generates a magnetic field all around it.
  8. Explanation of magnetism Electrons are perpetually rotating, and, since the electron has a charge, its spin produces a small magnetic moment. Magnetic moments are small magnets with north and south poles. The direction of the moment is from the south to the north pole.
