Cone magnet Ø 20/10 mm, height 8 mm

Neodymium, N38, nickel-plated
promptly deliverable


These cone magnets are neodymium magnets with special features: The magnetic flux lines are bundled on the small circular surface (10 mm), and therefore the magnets possess a high adhesive force (approx. 5 kg!). The base area has a diameter of 20 mm. The north pole is located on the small circular surface.

Cone magnets are perfectly suitable for the use on whiteboards, magnetic boards and other metal surfaces: The stump holds notes on the surface, but the magnet can be removed easily by turning it sideways. When you place the large base on a metal surface, however, it is hard to remove the magnet.

Due to the impressive adhesive force of almost 5 kg, cone magnets are hard to separate. Your best chance is to move them sideways to avoid pinching.
On the other hand, they can hold up to 25 A4 sheets on a whiteboard with no problem.

Cone magnets look very classy on a magnetic glass board. They still adhere well, despite the large distance to the metal.
The four available sizes of the cone magnet also look good together. The two larger magnets, however, are hard to separate.
