2. Iron filings - Wikipedia

   en.wikipedia.org/wiki/Iron_filings

   As the name suggests, iron filings can be obtained from metal working operations as the scrap material filed off larger iron and steel parts. [2] 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 ...

3. Ferromagnetism - Wikipedia

   en.wikipedia.org/wiki/Ferromagnetism

   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. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...

4. 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. [3]

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. 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) .

7. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   Due to ceramic ferrite magnet’s weaker magnetic fields compared to superconducting magnets, they are sometimes used in low-field or open MRI systems. [ 41 ] [ 42 ] These magnets are favored in certain cases due to their lower cost, stable magnetic field , and ability to function without the need for complex cooling systems.

   McRAE-HELENA, Ga. (AP) — Someone using a magnet to fish for metal objects in a Georgia creek pulled up a rifle as well as some lost belongings of a couple found slain in the same area more than ...

9. Pole piece - Wikipedia

   en.wikipedia.org/wiki/Pole_piece

   A magnet keeper is a specialised pole piece used to temporarily connect the poles of a permanent magnet, to help to preserve the magnetism, and for safety in the case of large and powerful magnets. Another specialised pole piece is the armature of an electromechanical solenoid , which produces work by being attracted by an electromagnet when ...
