Sphere size: Od 5mm silver bucky ball, quantity- 216 pieces, magnetic feature: 1) material: Sintered neodymiumÂironÂboron 2) max operating temp 80°c 3) grade: N35 4) coating: Ni 5) directions of magnetization : Top - north pole / bottom - south pole and thickness magnetized neodymium magnets have many industrial, education and household uses and are also very corrosive but only when handled with extreme care and precaution. It is best to nickel coated for long-term maximum energy output and usage. Neodymium magnets have a very high resistance to demagnetization. This makes them very useful in many different kinds of industrial applications. Their high energy products lend themselves to compact designs that result in innovative applications and lower manufacturing costs. Another major attribute of neodymium magnets that has added to their popularity is the affordability factor for educational and experimenters on their limited budgets. Safety guidelines : Due to strong magnetic fields of neodymium magnets needed to be handled with extreme care and precision to prevent accidents. Children should never be allowed to handle it and person who uses medical aids like a pacemaker. As the grade(magnetic power) goes high it becomes more fragile and brittle in nature, if mishandled its many small broken particle may scatter hence working with neodymium magnets utmost care must be taken to protect your hands and fingers and its essential to wear eye protective glass when handling because . Thus, if left near magnetic electronic media devices like computers, floppy disks, hard drives, credit cards, magnetic i.d. Cards, these magnets are likely to cause damage. These are never to be heated above 175o f or 80o c as they will loose their magnetic properties. In addition, they may catch fire and burn and produce toxic fumes."
