This small circular magnet has a diameter of 4mm, a thickness of 2mm, and is made of neodymium. It is the material chosen by most customers and weighs 0.19g. The surface magnetic field strength depends on the magnetic property level and magnetization direction you choose, usually greater than 3000 Gauss. Due to its small size, the tensile force is around 40g-60g, and is widely used in electronics, appliances, headphones, electronic components, sensors, toys, etc. If you need a large quantity, we will give you a surprising price.
Please note:
Small magnets have strong magnetic force, so they need to be handled carefully to avoid contact with the body or other objects. Especially for children and pets, small magnets should be placed out of their reach to prevent accidental ingestion or misuse.
Avoid collision and friction: Small magnets may break or produce magnetic debris during collision or friction, which may cause harm to the surrounding environment and personal safety. Therefore, it is important to avoid colliding or engaging in intense friction between small magnets and other objects.
