Single-Molecule Magnets: A New Class of .

A molecule with a large-spin ground state with D < 0 can function as a single-molecule magnet, as detected by techniques such as ac magnetic susceptibility. Out-of-phase ac signals (χ' 'M) were seen for complexes 1 and 1·2.5H2O to show that these complexes are single-molecule magnets. A sample of 1 was studied by ac susceptibility in the 0.4−6.4 K range with the ac field oscillating at ...

Ferrite (magnet) - Wikipedia

A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc. They are electrically nonconductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet.

Magnet Fishing - K&J Magnetics

Remember, the pull force you get from a magnet depends on what you're sticking it to. A powerful MMS-B-Z0 magnet can pull with hundreds of pounds of force when sticking to a solid steel surface (like the one that holds up a person in this video). If the steel object is smaller, though, the force could be a lot less. You won't see 300 lb of force from the magnet to a paperclip. What we ...
