The magnetic properties of tungsten wire are relatively weak, and it can be said that it basically has no magnetism. The following is a detailed explanation of the magnetic properties of tungsten wire:
- Basic properties of tungsten wire
Tungsten wire is a hard, high-melting-point metal material with a chemical symbol of W and an atomic number of 74. The melting point of tungsten wire is as high as 3410℃, making it one of the metals with the highest melting point known so far. In addition, tungsten wire also has the characteristics of good corrosion resistance and high strength.
- Definition and classification of magnetism
Magnetism is a property of a substance that is affected by magnetic force when placed in an uneven magnetic field. Magnetic materials can exhibit special magnetism under an external magnetic field, and such materials are called magnetic materials. Magnetic materials are divided into three categories: ferromagnetic materials, ferrimagnetic materials, and paramagnetic materials. Among them, ferromagnetic materials are further divided into two categories: soft magnetic materials and hard magnetic materials.
- Magnetic properties of tungsten wire
Although tungsten wire is a metal material, its electronic structure is different from typical magnetic materials such as iron and nickel. The electronic configuration of tungsten wire is closely related to the closed d layer, while in typical magnetic transition metals such as iron and nickel, the d layer is often half full, and this electronic configuration leads to their magnetism. In contrast, the electronic configuration of tungsten wire does not have the conditions for forming magnetism, so it is basically non-magnetic.
- Interaction between magnets and tungsten wire
Although tungsten wire itself is not magnetic, in some cases, magnets may have a weak attraction to tungsten wire. This is because tungsten wire is conductive, and when it is in a magnetic field, an induced current will be generated inside it, resulting in weak magnetism. However, this attraction is very small and is far from affecting the properties of tungsten wire.
