2. Bitter electromagnet - Wikipedia

   en.wikipedia.org/wiki/Bitter_electromagnet

   [3] [4] [5] By elongating the mounting and cooling holes, there is a substantial drop in the stresses developed in the system and an improvement in cooling efficiency. As the stresses increased in the original bitter plates, they would flex slightly causing the small circular cooling holes to move out of alignment reducing the efficacy of the ...

3. Neodymium magnet - Wikipedia

   en.wikipedia.org/wiki/Neodymium_magnet

   A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet .

4. Magnetic switchable device - Wikipedia

   en.wikipedia.org/wiki/Magnetic_switchable_device

   A round permanent magnet is inserted into the bored hole and a handle is attached to allow rotation of the magnet. This act of rotation changes the orientation of the magnetic field. [4] In the off position, the poles are oriented towards the non-ferrous core.

5. Electromagnet - Wikipedia

   The disks are pierced with holes through which cooling water passes to carry away the heat caused by the high current. The strongest continuous field achieved solely with a resistive magnet is 41.5 T as of 22 August 2017, produced by a Bitter electromagnet at the National High Magnetic Field Laboratory in Tallahassee, Florida.

6. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   Magnetic viewing film showing a flat refrigerator magnet's magnetization. Flat flexible (not hard ceramic ferrite) refrigerator magnets are created with a Halbach magnetization pattern for a stronger holding force when attached to a flat ferromagnetic surface (e.g. a fridge door) than the holding force from a uniform magnetization.

7. Samarium–cobalt magnet - Wikipedia

   en.wikipedia.org/wiki/Samarium–cobalt_magnet

   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.
