Sphere Magnet General Information

Below are some common questions about neodymium sphere magnets, magnetic balls and their properties and uses.

What is a sphere magnet?

A sphere magnet is a round, ball-shaped permanent magnet, sometimes called a ball magnet or magnetic sphere. Our sphere magnets are made from neodymium (NdFeB), the strongest type of permanent rare earth magnet commercially available.

Where are the north and south poles on a sphere magnet?

A typical axially magnetized sphere magnet has its north and south poles on opposite sides of the sphere. The magnetic field is concentrated near these two poles, and the sphere can rotate freely to align its poles with another magnet or magnetic material.

What are sphere magnets used for?

Neodymium sphere magnets are used in consumer products, crafts, hobbies, DIY projects, science experiments, demonstrations, displays, models, magnetic assemblies and other applications. Their spherical shape is especially useful when a magnet needs to rotate, pivot or align itself with a magnetic field.

Are neodymium sphere magnets strong?

Yes. Neodymium sphere magnets can produce surprisingly strong magnetic forces for their size. The actual strength depends on the diameter, magnet grade, distance from the magnetic material and how the magnet is being used.

How are sphere magnets different from disc and block magnets?

Unlike flat disc and block magnets, sphere magnets have no flat mounting surface and can easily roll or rotate. Their spherical shape allows them to change orientation and align their magnetic poles, making them useful for applications where movement, rotation or magnetic alignment is desired.

What sizes of neodymium sphere magnets are available?

Neodymium sphere magnets are available in a range of diameters, from tiny magnetic balls for small projects and assemblies to larger sphere magnets that provide substantially greater magnetic force. Choose a diameter based on the space available and the strength required for your application.
