Typical magnet fishing equipment, including protective gloves, a bucket for storing catches, antibacterial hand gel, and a neodymium magnet attached to a rope. Magnet fishing is typically done with gloves, [10] a strong neodymium magnet secured to a durable rope between 15 and 30 meters (50–100 ft), and sometimes a grappling hook as a supplement to the magnet.

Ferrofluid is a liquid that is attracted to the poles of a magnet.It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1]
A 1996 study by Lawrence Livermore National Laboratory found no significant effect of magnetic water treatment on the formation of scale. As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental ...
Neodymium magnet on a mu-metal bracket from a hard drive. Neodymium magnets (an alloy, Nd 2 Fe 14 B) are the strongest permanent magnets known. A neodymium magnet of a few tens of grams can lift a thousand times its own weight, and can snap together with enough force to break bones.
Masato Sagawa (佐川眞人; born August 3, 1943, in Tokushima, Japan) is a Japanese scientist and entrepreneur, and the inventor of the sintered permanent neodymium magnet (NdFeB). Sagawa was awarded the Japan Prize and IEEE Medal for Environmental and Safety Technologies for his efforts.
You can avoid problems with your magnetic strip by switching to a more modern card with an EMV chip. While not foolproof , these cards tend to provide a higher level of security while avoiding the ...
The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a ferrous metal surface, even causing broken bones.

Diamagnetic levitation can be inherently stable. A permanent magnet can be stably suspended by various configurations of strong permanent magnets and strong diamagnets. When using superconducting magnets, the levitation of a permanent magnet can even be stabilized by the small diamagnetism of water in human fingers. [15]
