Characteristics and Types Analysis of Neodymium Ball Magnets

Characteristics of Neodymium Ball Magnet


  • Neodymium sphere magnets are commonly available in sizes of 5 mm, 6 mm, 8 mm, 10 mm, 12.7 mm and 19 mm.

  • The magnetic force of neodymium sphere magnets ranges from 130 g to the largest 23 kg.

  • Neodymium sphere magnets bulk can be coated with nickel (Ni-Cu-Ni) or chrome, gold for an elegant appearance.

  • Customized sizes range from small neodymium sphere magnets with a diameter of 2 mm to large ones with a diameter of 50 mm.


Types of Neodymium Ball Magnets


Neodymium ball magnets with a diameter of 5 mm


5 mm is a small size for spherical rare-earth neodymium magnets, which are sold by all magnet dealers. The common coatings of 5 mm neodymium sphere magnets include nickel, chrome, gold, and silver. Various colors of 5 mm neodymium magnetic balls are used for neocube magnetic puzzle toys, and we can provide 216 cube-shaped neodymium ball magnets with a diameter of 5 mm.


The tensile range of our 5mm magnetic balls wholesale is 0.8-1.2 lb. It is dangerous for children under the age of 3 to play with small neodymium magnetic balls.


Neodymium sphere magnets with a diameter of 8 mm


8 mm spherical rare earth neodymium magnets are the most popular size for most magnet dealers. They are usually nickel-plated and chrome-plated, and other coatings can be customized. All grades from N35 to N52 are available for 8 mm neodymium ball magnets. Bulk quotes are cheaper, and special packaging can be provided upon request.


Neodymium sphere magnets with a diameter of 10 mm


This is the most popular size for spherical neodymium magnets with a diameter of 10 mm. Neodymium material is much stronger than ferrite. The strongest neodymium sphere magnet with a diameter of 10 mm can generate a magnetic force of about 2.2 kg. Nickel and chrome are common coatings for 10mm spherical neodymium magnets. All grades of 10 mm neodymium ball magnets are available. Magnetic balls are not suitable for children under 3 years old. It can cause bodily harm if swallowed.


Neodymium sphere magnets with a diameter of 12.7 mm


12.7 mm is an intermediate size for spherical rare-earth neodymium magnets and is also a popular size in the US market. The tensile force of N42 neodymium sphere magnets with a diameter of 12.7 mm is about 2.7 kg, and higher grades can be customized for greater force. Most 12.7mm neodymium sphere magnets are nickel-plated or chrome-plated, and other coatings such as gold and silver can be customized. If two strong magnets collide, the coating at the contact point may fall off due to the strong impact force. Do not let children play with magnetic balls alone.


Neodymium ball magnets with a diameter of 15 mm


15 mm is a large size for spherical neodymium magnets with ultra-strong tensile force. It's not easy to separate these strong sphere magnets from each other without plastic spacers. 15mm magnetic balls are usually made of N35 grade and coated with chrome or nickel. You must handle strong magnetic balls with care. If two strong magnetic balls collide, the coating at the point of impact will fall off due to the huge impact force. Strong magnetic balls are definitely not toys for children! Other grades and coatings can be customized.
