Fuse beads are sold in a variety of sizes, but most have diameter 5 mm, and 5 mm Hama beads are compatible with 5 mm Perler beads. [1] Hamabeads come in three sizes: mini (2 mm), midi (5 mm) and maxi (10 mm). [7] Perler beads come in two sizes called classic (5 mm) and biggie (10 mm). Pyssla beads (by IKEA) only come in one size (5 mm).
This magnetic energy value is about 18 times greater than "ordinary" ferrite magnets by volume and 12 times by mass. This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend ...
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. [43]
A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
