tungsten carbide magnetic properties are dependent on the tungsten, cobalt, or nickel used as a binder. The ratio of tungsten to cobalt determines the hardness and toughness of the alloy, while the amount of nickel determines how corrosion-resistant it is.
Like all metals, tungsten has a hardness on the Mohs scale that is measured in abrasion resistance. This hardness is the result of a combination of the metal's strength and its ability to resist oxidation at high temperatures.
It's a very durable material that can be used for a wide range of applications. For example, tungsten can be alloyed with carbon to create a material that is very scratch-resistant. This makes it a good choice for many types of equipment and tools.
Aside from its physical attributes, tungsten has another advantage that can help you find it in the event you lose it: It's magnetic!
While tungsten isn't a naturally magnetic metal, it can be magnetized by passing a magnet near it. This happens because a small electric field sets up in the metal, which can interact with the magnet.
The magnetic attraction of a ring is based on this same principle. When you spin the ring, it sets up a small electric current that has its own magnetic field of its own.
This can be seen by putting a magnet on the surface of the ring. The magnet sets up an electric field of its own, which then interacts with the ring's magnetic field to create the magnetism that allows it to be spun.
