Alnico magnets are produced by casting or sintering processes. [9] Cast alnico is produced by conventional methods using resin bonded sand molds, which can be intricate and detailed, thereby allowing for complex shapes to be produced. [10] The produced alnico magnet typically has a rough surface. [11]
The Best Foods to Cook In a Cast-Iron Skillet Seared Meats. Searing meat is probably what we use our cast-iron skillet for the most often. The pan's unparalleled heat retention ensures a perfect ...
Most common audio magnets, including those used in loudspeakers and electromagnetic instrument pickups, are ferrite magnets. Except for certain "vintage" products, ferrite magnets have largely displaced the more expensive Alnico magnets in these applications. In particular, for hard hexaferrites today the most common uses are still as permanent ...
Terfenol-D (terbium, dysprosium, and iron), a highly magnetostrictive alloy used in portable speakers such as the SoundBug device; Ferrocerium (cerium, iron) Neodymium magnets, another strong permanent magnet; SmCo ; used for permanent magnets in guitar pickups, headphones, satellite transponders, etc. Scandium hydride
If we rotate one of the hard magnets (north pole point down), the iron U on top will see a north pole and a south pole. The other iron U will see exactly the opposite. In this way almost all the magnetic flux will be concentrated inside both iron U's creating a close circuit for the magnetic field (because the high permeability of the iron).

By: Kerri-Ann Jennings, M.S., R.D. Cast-iron skillets might seem like an old-fashioned choice in the kitchen. But this dependable cookware is a must in the modern kitchen. Cast-iron skillets ...
A "horseshoe magnet" made of Alnico 5, about 1 inch high.The metal bar (bottom) is a keeper. A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic ...
