Neodymium Magnetic Balls
https://www.magnet4sale.com/Sphere-magnets/ball-magnets/Neodymium magnetic balls are the strongest, most durable and versatile magnetic balls available. They come in different sizes and strengths to address different industries’ needs. Neodymium is a synthetic magnet made from a metal that is twice as strong as steel. It is used in the manufacture of strong magnetic balls, wristwatches, cufflinks, rings and other fashion accessories.
There are several advantages to using Neodymium magnetic balls. They are durable, strong enough to be used as a weight management tool. They are available in both standard and half-inch size and in a wide range of strengths. Because they use a surface area about ten times larger than that of a penny, they can maintain their grip even under the toughest magnetic balls and come in handy. The standard sized Neodymium ball has an outer surface area of about five thousandths of an inch or less, which makes it ideal for clothing accessories and similar applications. The half-inch size magnetic balls a full one-fourth of an inch and is ideal for watches, cufflinks, rings and many other items.
Because nickel is a non-magnetic metal it was not considered a good choice for jewelry and thus the creation of Neodymium magnetic balls with nickel traces was not undertaken. However, because nickel is extremely hard and durable the nickel magnetic balls were found to be much superior to the traditional ones that did not contain nickel. These balls are available in sizes ranging from five millimeters up to twenty-two millimeters. A unique feature of these magnetic balls is that they are extremely stable, able to retain their grip even after coming into contact with a considerable amount of force. They have also been found to work exceptionally well in water.
