Neodymium Cylinder Magnet – 4mm x 5mm | N45
Available in stock
This popular Rare Earth cylinder magnet measures 4mm in diameter and 5mm in height. It is an N45 grade magnet with a magnetic flux density of 6327 Gauss and a pull force of 0.607 kilograms. Identified by part number NR0405, its cylindrical shape produces a focused and strong magnetic field, making it ideal for detecting metal screws and nails within drywall and locating timber studs.
Commonly used in commercial stud finders and similar magnetic tools, these small cylinder magnets are versatile and well-suited for applications such as delicate woodwork or ceramics, where a secure hold with minimal visual impact is required. Their size allows easy installation into 4mm drill holes.
Pull Force Information
Pull Force Information
Pull force refers to the maximum holding strength of a magnet. Measured in kilograms, it represents the amount of weight a magnet can support when attached to 10mm thick mild steel, with full, flat, and direct surface-to-surface contact.
A magnet's pull force can be affected by several factors, including its orientation (horizontal vs. vertical) and the presence of any air gaps between the magnet and the surface it’s attached to.
