Ferrite Cylinder Magnet - 22mm x 25mm
Ferrite Cylinder Magnet - 22mm x 25mm
Available in stock
This ferrite cylinder magnet measures 22mm in diameter and 25mm in height, identified by part number FR2225, with a pull force of 2 kg. 
Commonly used in reed switches, these magnets control electrical circuits by opening or closing contacts based on magnetic proximity. When near the magnet, the reed switch completes the circuit, activating the device; when the magnet moves away, the circuit breaks, turning the device off. This magnetic switching principle is applied in numerous systems, from railway track controls to laptop lid sensors.
Despite their brittleness, ferrite cylinder magnets are essential components in DC motors found in household appliances and power tools, offering reliable, secure, and reusable magnetic engagement across various industrial and hobby applications.
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.
