Circular magnets mainly have holes and no holes. Some netizens asked what is the difference between circular magnets with holes and magnets without holes? Today, courage magnet Xiaofu will give you a brief introduction on this issue.


The main difference between a round magnet with a hole and a hole without a hole is the use, in addition to the price, there are also differences in the magnetic force.

round magnet with hole


For example, if you need to fix or set the magnet in a certain place, you can choose this kind of magnet with holes. The hole diameter can be processed by the magnet manufacturer according to your actual needs. The size of the magnet with holes has three data, namely outer diameter and inner diameter. , and thickness, a circular magnet without a hole has a diameter and thickness.


In terms of price, round hole magnets are more expensive because of the extra drilling process.


In terms of magnetic force: if the light is from the highest point of magnetic force, the magnetic force of the hole in the middle hole of the perforated magnet is greater than the surface magnetic force of the non-perforated magnet. If compared from the suction force, the suction force will be small because the magnetic area of the hole is reduced.


The above is the introduction of the difference between round magnets with holes and those without holes. If you simply want to fix the magnets, you can also use the method of sticking adhesive on one side of the magnets. Depending on your preference, our company can customize the round magnets according to your needs. Magnet through holes, countersunk holes, small holes, large diameter holes, etc., welcome to consult for quotation.
