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.

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.
Magnetic 2D materials can be used as a part of van der Waals heterostructures. They are layered materials consisting of different 2D materials held together by van der Waals forces. One example of such structure is a thin insulating/semiconducting layer between layers of 2D magnetic material, producing a magnetic tunnel junction.
Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3 ) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]
The article mentions toys containing neodymium magnets the size and shape of aspirin tablets. Can someone please replace this with a proper measurement? Even the original Bayer Aspirin is available in different shapes and sizes, let alone all the different stuff called "Aspirin" which is available in the USA. --BjKa 13:52, 8 November 2006 (UTC)
A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .
