Nowadays, many products use small-sized magnets, some of which are ring, some are circular, some are arc-shaped, cylindrical, and so on. Today, this article focuses on introducing small-sized rectangular magnets, including their uses, pull strength, commonly used materials, drawings, selection, and purchasing suggestions.
Small rectangular magnets are briefly described;
Small rectangular magnets generally refer to rectangular magnets with dimensions of a few millimeters in length, width, and height. There are three dimensions available, with common sizes being 3x2x1mm, 5x2x1mm, and 10x5x1mm. The most commonly used material is neodymium, followed by samarium cobalt and ferrite.

Typical uses of small rectangular magnets;
Bluetooth Headset, Magnetic Data Cable, Magnetic Connector, Magnetic Switch, Packaging Box, Arts and Crafts, Smartphone and so on.
Small rectangular magnet pulling force data reference;
5x4x2mm N42 neodymium block magnet, vertical pull force about 0.45kg.
5x2x0.5mm tiny rectangle neodymium magnet, N42 grade vertical pull about 0.1kg
5x1.5x1mm tiny neodymium rectangle magnet, N45 grade vertical pull about 0.19kg
10x4x1.5mm rectangle neodymium magnet with N35 grade pull force about 0.6kg.
The pulling force of small rectangular magnets is related to the material, grade, magnetization direction, size and so on, like neodymium material pulling force is usually around 100g-1kg.

When shopping for small rectangular magnets, you need to consider the application environment, pulling force. Like neodymium iron boron is suitable for high tension requirement scenario, samarium cobalt is suitable for high temperature above 220℃ environment, ferrite is suitable for low magnetic requirement scenario.
