China Manufacturer wholesale strong rare earth magnet NdFeb Neodymium Cylinder magnet
Neodymium( NdFeB )magnets are the strongest type of rare earth magnet. Rod (cylinder) magnets are long, circular magnets where the length exceeds the diameter, commonly used for recessing into a drilled hole for holding applications where larger magnetic fields are required. With superior size to strength ratio, magnetic rods & bars are suitable for a wide range of applications. Over 15 Years Experience Neodymium Magnet Manufacturer, Bearheart neodymium rods and cylinders come in a variety of sizes, dimensions and grades. They are handy, all-purpose magnets commonly used in the art display industry, mining, engineering, construction, lighting, teaching facilities and for many other commercial and industrial purposes.

Magnetization Direction for Neodymium Magnets
Disc and Cylinder magnets can be axially or diametrically magnetized.
What is the use of cylinder magnet?
Neodymium cylinder magnets are typically used in medical, sensor, read switches, meters, and holding applications. Neodymium Cylinder magnets can be magnetized through the length or across the diameter. The shape of a neodymium cylinder magnet produces a magnetic field with a longer reach.

FAQ:
Q1. Are neodymium magnets diametrically magnetized?
A1. This neodymium magnetic disc is diametrically magnetized, which means it is magnetized across the diameter. When the disc is sitting flat on a surface, the north and south poles are located on the curved sides, at opposite sides.
Q2. What is a diametrically magnetized magnet?
A2. Diametrically magnetized magnet refers to the magnetization direction is through its diameter. The north pole and the south pole are located on the curved surface at opposite sides, respectively.
Q3. What is neodymium magnet in cylinder shape?
A3. Neodymium cylinder magnets are typically used in medical, sensor, read switches, meters, and holding applications. Neodymium Cylinder magnets can be magnetized through the length or across the diameter. The shape of a neodymium cylinder magnet produces a magnetic field with a longer reach.
Q4. What can demagnetize a neodymium magnet?
A4. It takes a big ac field to demagnetize those magnets at room temperature. You can demagnetize them by heating them to the Curie temperature, but that may be inconveniently high, e.g. 350°C. Another option is to heat to some lower temperature and apply a smaller ac field than would be needed at room temperature.
Q5. What is the direction of a neodymium magnet?
A5. Our neodymium ring magnets and our ferrite ring magnets are axially magnetised, unless noted otherwise. That means, the direction of the north-south axis runs parallel to the diameter. If a ring magnet is diametrically magnetised, it means the direction of the north-south axis runs parallel to the height.
