2. Horseshoe magnet - Wikipedia

   en.wikipedia.org/wiki/Horseshoe_magnet

   The shape of the magnet was originally created as a replacement for the bar magnet as it makes the magnetic field stronger for a magnet of comparable strength. [5] A horseshoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic ...

   Astronomers on Wednesday announced that they have detected a strong and organized magnetic field twisted in a spiral pattern around the Milky Way's supermassive black hole, revealing previously ...

4. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   The magnetic flux produced by this ideal design would be perfectly uniform and be entirely confined to either the bore of the cylinder or the outside of the cylinder. Of course, the ideal case of infinite length is not realizable, and in practice the finite length of the cylinders produces end effects, which introduce non-uniformities in the field.

5. Alnico - Wikipedia

   en.wikipedia.org/wiki/Alnico

   Therefore, alnico can produce a strong magnetic flux in closed magnetic circuits, but has relatively small resistance against demagnetization. The field strength at the poles of any permanent magnet depends very much on the shape and is usually well below the remanence strength of the material.

   A new image of the black hole that lies at the center of our Milky Way galaxy shows that it is surrounded by a strong, twisting magnetic field. New image reveals spiraling magnetic field around ...

7. Bitter electromagnet - Wikipedia

   en.wikipedia.org/wiki/Bitter_electromagnet

   The strongest continuous magnetic fields on Earth have been produced by Bitter magnets. The strongest continuous field achieved solely with a resistive magnet is 41.5 tesla as of 22 August 2017 [update] , produced by a Bitter electromagnet at the National High Magnetic Field Laboratory in Tallahassee , Florida .
