This is a ring magnet with a straight hole in the middle, it can also be called a circular magnet with a hole, the diameter of 12mm, the thickness of 3mm, the size of the hole can meet your requirements, such as 2mm, 3mm, 4mm can be, the type of hole can also be countersunk, the magnetic strength of the table is higher than 3000 Gauss, if you need a low price can contact us courage magnet manufacturers, the larger the amount, The lower the price.

Choose straight hole or countersunk hole magnets, depending on the specific application and needs, straight hole magnets have through holes, that is, the two ends of the magnet are straight through. This design can provide strong magnetic concentration and magnetic field transmission, suitable for many application scenarios. Straight hole magnets are often used in applications such as adsorption, fixation, sensing and excitation of magnetic fields,

Countersunk magnet: A countersunk magnet forms one or more depressions or holes on the surface of a magnet. This design can make the magnetic force more concentrated and focused, reducing the loss of magnetic force in space. Countersunk magnets are commonly used in applications that require concentrated magnetic force, such as magnetic grippers, magnetic stirrers, etc.
