  2. Human magnetism - Wikipedia

    en.wikipedia.org/wiki/Human_magnetism

    People alleged to have such an ability are often called human magnets. Although metal objects are the most prevalent material of attraction, some "human magnets" are also able to stick other types of materials to their skin, such as glass , porcelain , wood or plastic as well as metals with no ferromagnetic properties, such as brass and ...

  3. Magnetic alloy - Wikipedia

    en.wikipedia.org/wiki/Magnetic_alloy

    A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .

  4. Iron filings - Wikipedia

    en.wikipedia.org/wiki/Iron_filings

    Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet. The south pole of each particle then attracts the north poles of its neighbors, and this process is repeated over a wide area creates chains of filings parallel to the direction of the magnetic field.

  5. Magnetism - Wikipedia

    en.wikipedia.org/wiki/Magnetism

    Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

  6. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    Paramagnetism, ferromagnetism, and spin waves. 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.

  7. Magnet - Wikipedia

    en.wikipedia.org/wiki/Magnet

    A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...

  9. Magnetic separation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_separation

    Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. [1] Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. [1] Magnetic separation is also useful in mining iron as it is attracted to a magnet.
