    1 Between magnets, it is the attraction of unlike magnetic poles for each other and the repulsion between like magnetic poles 2 between a magnetic field and a moving charge: the deflecting force is perpendicular to the velocity of the charge and perpendicular to the magnetic field lines.

  • Molten iron can not be magnetized | Physics Forums

    Apr 08, 2011· Again, molten iron I would suppose is excluded due to its inability to hold or maintain a magnetic field. Please clarify. In analogy with the description of the core of the rotating Earth, we could take a jar of salt water and put it on a spinning turntable.

  • Magnet Wikipedia

    A magnet is a material or object that produces a magnetic magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

  • How Magnets Work | HowStuffWorks

    Iron filings (right) align along the magnetic field lines of a cylindrical neodymium magnet. To understand the answers to these questions, it helps to have a basic definition of a magnet. Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt.

  • How do magnets work? Cool Experiments with Magnets

    In a hard magnetic material (alloys of iron such as Alnico, some steels, neodymiumironboron, etc), most of the domains will remain aligned, so that you will be left with a strong magnet. Since the ending point is not the same as the starting point for magnetic materials, they have what is called hysteresis. Magnetic Poles. 1.

  • Electrons and Why Magnets Stick | HowStuffWorks

    Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment. The magnetic moment is a vector it has a magnitude and a direction. It''s related to both the magnetic field strength and the torque that the field exerts.

  • Is Nickel Magnetic University Of Maryland

    Most metals aren’t magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium. Because Nickel (Ni) is ferromagnetic it is used in making Alnico magnets (consisting of aluminium , nickel , and cobalt ).

  • Why Magnets Have No Effects on Some Metals | Sciencing

    Ordinarily, the magnetic fields are not aligned, and so a lump of iron metal by itself has no net magnetic field; the randomly aligned magnetic fields of individual atoms cancel each other out. When an external magnetic field is applied, however, the atoms line up with it, so the object becomes magnetized.

  • Chemistry for Kids: Elements Iron Ducksters

    Iron is the most naturally magnetic of the elements. Other naturally magnetic elements include cobalt and nickel. Iron becomes significantly harder when alloyed with other elements such as carbon. Iron can be found in four allotropic forms. The most stable form of iron at normal temperatures is alpha iron which is commonly known as ferrite.

    Silicon iron as a magnetic material was developed by Sir Robert Hadfield in England, and was introduced to the United States by the Allegheny Steel Company in 1903. As silicon is added, the iron becomes a better and better magnetic material as its electrical resistivity increases, but it also becomes brittle and difficult to work.

  • Why do magnets attract only iron? Quora

    A magnetic field is basically electrones from the magnet moving from the north (negative) side of the magnet to the south (positive) side. The electrons from the magnetic field are atracted to the protons of the iron, thus creating a force between...
