  • Ferromagnetism - Wikipedia
    Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet
  • Ferromagnetism | Definition, Cause, Examples, Uses, Facts | Britannica
    ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets
  • Paramagnetic vs Diamagnetic vs Ferromagnetic – Magnetism
    Diamagnetism, paramagnetism, and ferromagnetism are the three main types of magnetism seen in materials Other types include antiferromagnetism, ferrimagnetism, superparamagnetism, and metamagnetism But, understanding the three main types is a good introduction to the concept
  • Ferromagnetism - HyperPhysics
    Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets
  • Ferromagnetism: Definition, Properties, Examples, and Applications
    Ferromagnetism is an exciting phenomenon observed in certain materials, known as ferromagnetic materials, that can retain their magnetization even after removing an external magnetic field Ferromagnetic materials can become ferromagnets and interact strongly with other magnets and magnetic fields
  • Ferromagnetism - Definition, Causes, Properties, Hysteresis
    Ferromagnetism is a physical phenomenon (long-range ordering) in which certain materials, such as iron, are attracted to one another strongly Rare earth minerals including gadolinium contain ferromagnets
  • 36 Ferromagnetism - The Feynman Lectures on Physics
    In this chapter we will discuss some materials in which the net effect of the magnetic moments in the material is much greater than in the case of paramagnetism or diamagnetism The phenomenon is called ferromagnetism
  • Ferromagnetism - Engineering LibreTexts
    Ferromagnetic materials contain unique magnetic moments that are aligned parallel to each other, all in the same direction (Figure 2) All other types of magnetization have moments in more than one direction Ferromagnetism is the only magnetization with all same direction moments
  • What is Ferromagnetism? - BYJUS
    Ferromagnetism is a physical phenomenon (long-range ordering), in which certain materials like iron strongly attract each other Ferromagnets occur in rare earth materials and gadolinium
  • Ferromagnetism - an overview | ScienceDirect Topics
    Ferromagnetism is the basic method in which a compound forms a permanent magnet or is attracted to a magnetic field In a nonmagnetic compound, permanent magnetic dipoles tend to line up antiparallel in order to cancel each other out In ferromagnetism, however, the opposite is true
