Product Description

Neodymium magnets are a combination of Neodymium, Iron, and Boron which extremely strong for their size. Cylinder magnet is also referred to as Neodymium rod magnet. It is similar with Neodymium disc magnet that Neodymium cylinder magnet is measured according to the diameter (D) and length (L), where the length is equal to or exceeds the diameter. The higher L/D ratio enables the axially magnetized Neodymium cylinder magnets have higher gauss value and making it well suitable for activating hall sensor and reed switch. In addition, Neodymium cylinder magnet with higher L/D ratio can also generate much stronger pull force from the relatively small magnetic pole area and exhibit superior temperature stability. Other representative application of Neodymium cylinder magnet includes magnetic bead separation rack and some holding applications.
