Power magnet, Ring 10x4x15 mm.

Very strong magnets made of neodymium. You can put a string or rope through the hole.

Diameter: 1 cm.
Height: 1.5 cm.
Hole size: 0.4 cm.
Strength: approx. 3.3 kg.

This magnet is a ring magnet but also a rod magnet. As the diameter is smaller than the length, it is called a rod magnet.

SPECIFICATIONS

The direction of the magnetism is axial on this magnet (as most other magnets). But you will find that it is also quite strong on the sides, although the strongest field is situated around the North direction and South direction of the poles, that are placed on the plane surfaces of these magnets.
