About 29 super strong neodymium magnet balls link together to form a chain that is about 7 inch long and can form a bracelet. Worn as a jewelry item by magnet enthusiasts and those who believe in the healing power of magnets. Magnet balls can be pulled apart and re-attached as needed. Each magnet is a neodymium grade N35 super strong magnet with a diameter of 0.25 inch (about 6 mm).
A neodymium magnet (a special type of rare-earth magnet) is a powerful magnet made of a combination of neodymium, iron, and boron — Nd2Fe14B.
These magnets are very strong in comparison to their masses, but are also mechanically fragile and loose their magnetism if heated to temperatures above 80 degrees Celsius.
Neodymium magnets are graded in strength from N24 to strongest N48 (strongest). These magnets are N35 strength with .25" diameter.
Warning: Keep out of reach of children who may swallow magnet balls or break them by rough handling or dropping them on a hard ground.
