What are three examples of ferromagnetic materials?
Iron, nickel, and cobalt are examples of ferromagnetic materials.
What is ferromagnetism in chemistry with example?
Ferromagnetism: The substances that are strongly attracted by a magnetic field are called ferromagnetic substances. Ferromagnetic substances can be permanently magnetised even in the absence of a magnetic field. Some examples of ferromagnetic substances are iron, cobalt, nickel, gadolinium, and CrO2.
Can electricity control magnetic fields?
Scientists have managed to use electrical fields to control the magnetic oscillations of certain ferrous materials. This has opened up huge potential for computer technology applications, as data is currently transferred in the form of electrical signals but stored magnetically.
What are the applications of ferromagnetism?
Ferromagnetism is very important in industry and modern technology, and is the basis for many electrical and electromechanical devices such as electromagnets, electric motors, generators, transformers, and magnetic storage such as tape recorders, and hard disks, and nondestructive testing of ferrous materials.
What is a ferromagnetic object and give an example of one?
Ferromagnetic materials are those which are strongly magnetized even in the absence of an external magnetic field. Examples of ferromagnetic materials are: Iron, nickel, cobalt, gadolinium and their alloys.
What are the types of ferromagnetism?
Some of the examples of ferromagnetic materials are cobalt, iron, nickel, gadolinium, dysprosium, permalloy, awaruite, wairakite, magnetite, etc….What are the Ferromagnetic Materials?
Ferromagnetic Materials | Neodymium Magnet |

What is ferromagnetism with Example Class 12?
Magnetic moments of the domains in the substance are aligned in parallel and anti-parallel directions in unequal numbers. They are weakly attracted by magnetic field as compared to ferromagnetic substances. For example, Fe3O4 (magnetite) and ferrites like MgFe2O4 and ZnFe2O4.
What is ferromagnetism in Class 12 examples?
Ferromagnetic substances get strongly attracted towards magnetic field. They can be permanently magnetized. For example, iron, cobalt, nickel, gadolinium and CrO2 are ferromagnetic substances.
What are some examples of magnetism?
The most familiar example of magnetism is a bar magnet, which is attracted to a magnetic field and can attract or repel other magnets. Ancient people used lodestones, natural magnets made of the iron mineral magnetite.
What is the cause of ferromagnetism in some materials?
Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. The magnetism in ferromagnetic materials is caused by the alignment patterns of their constituent atoms, which act as elementary electromagnets.
Are compass needles ferromagnetic?
By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials. The needle of a compass is itself a permanent magnet and the north indicator of the compass is a magnetic north pole.
