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.
Pewter plate Artisans working with tin sheets. Tin in combination with other elements forms a wide variety of useful alloys. Tin is most commonly alloyed with copper. Pewter is 85–99% tin, [97] and bearing metal has a high percentage of tin as well. [98] [99] Bronze is mostly copper with 12% tin, while the addition of phosphorus yields ...
A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt.. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton.
They are very often used in science demonstrations to show the direction of a magnetic field. 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 ...
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 ...

Alnico alloys can be magnetised to produce strong magnetic fields and have a high coercivity (resistance to demagnetization), thus making strong permanent magnets. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger.
A bubble chamber at Argonne National Laboratory has a 4.8-meter-diameter Nb-Ti magnet, which produces a magnetic field of 1.8 tesla. [5] About 1,000 Nb-Ti SC magnets were used in the 4-mile-long main ring of the Tevatron accelerator at Fermilab. [6] The magnets were wound with 50 tons of copper cables, containing 17 tons of Nb-Ti filaments. [7]
