Superconductors, diamagnetic, paramagnetic, and ferromagnetic, are four separate kinds of superconductors that are strongly repelled, weakly repulsed, weakly attracted, and strongly attracted to magnets, respectively. The exception to all four is paramagnetic, which permits non-ferrous metals to display modest magnetism.
Is Tungsten Magnetic, then? Because of the presence of unpaired electrons and the realignment of those electron pathways due to an external magnetic field, tungsten is partially magnetic or paramagnetic in nature. As a result, magnetic attraction is feeble.
What is the definition of paramagnetism?
Paramagnetism is a type of magnetism in which some elements are attracted weakly by an external magnetic field and produce their magnetic field in the same direction as the applied external magnetic field.
The presence of unpaired electrons in the atom of the material causes this feature. Aluminum, iron oxide, oxygen, and other substances with this characteristic are examples.
Why does Tungsten have paramagnetism?
The existence of unpaired electrons in an atom’s outermost shell causes this.

When electrons spin, they create a magnetic dipole moment, causing them to behave like tiny magnets.
When an external field is present, the electrons spin parallel to one other, generating a net attraction.
What is the best way to tell if an element is paramagnetic?
The most straightforward way is to draw the element’s electrical arrangement and look for unpaired electrons.
The element is paramagnetic if it is present; otherwise, it can be a superconductor, diamagnetic, or ferromagnetic.
Tungsten is a paramagnet due to the presence of four unpaired electrons in the 5d shell, as seen in the diagram above.
When electrons spin, they create a magnetic dipole moment, causing them to behave like tiny magnets. When an external field is present, the electrons spin parallel to one other, generating a net attraction.
Will Tungsten be attracted to a magnet?
No. A static magnetic field of a magnet will not attract Tungsten since it is a paramagnet.
A quickly changing magnetic field, on the other hand, will produce an electric current in the Tungsten, which will reject the magnetic field, causing the Tungsten to fly far and fast.
Try spinning a Tungsten ring as an experiment. The ring’s charge is similar to a current.
A positive charge should, in theory, cancel out a negative charge, but in practise, or locally, it does not. Weak magnetism is induced by the fluctuating electric field, which reacts to an external magnetic field.
An electric field generated by a changing magnetic field is required for such a phenomena. A current is created by passing a magnet in and out of a ring. Because they reject each other, the ring will either fly away or hit you severely.
Is it true that tungsten carbide is magnetic?
It is dependent on the binder used in the alloying process.
The magnetic property of tungsten carbide is determined by either the Cobalt or Nickel binder. Furthermore, cobalt attracts a magnet powerfully, but nickel does not.
So, if the Tungsten Carbide binder contains nickel, it will not attract a magnet, however if the binder is cobalt, it would.
Will tungsten carbide be detected by a metal detector?
Yes, a metal detector can detect Tungsten even if the ratio of Tungsten to carbon is 50.
Because the electrical conductivity of Tungsten carbide does not alter dramatically when a metal detector comes into contact with it.
A metal detector is surrounded by a magnetic field created by electricity flowing via a coiled wire. The atoms of another metal, such as tungsten or tungsten carbide, are affected when the detector is swept across them.
It alters the movement of electrons in the metal. An electric current is induced by a changing magnetic field, which leads to magnetism.
It doesn’t matter if carbide is present or not, once you know it. Tungsten is basically reacting to the metal detector’s magnetic field. Carbide has no effect on electrical current flow in any form.

Tungsten’s magnetic susceptibility
Where the real calculation can be done using the Brillouin function, the graph plainly shows the value to be quite low. It confirms that Tungsten has modest to very weak magnetic.
Tungsten’s Brillouin function
The ions of iron ammonium alum, Chromium, Gadolinium sulphate octahydrate, and Potassium alum, as well as Tungsten and its alum, all follow a similar trend.
The Brillouin function, which aids in the calculation of the magnetization of ideal paramagnets, is strictly followed by tungsten.
Values become constant after reaching a particular point, as shown in the graph. It confirms that given a constant external magnetic field, the Tungsten’s intrinsic magnetic field becomes constant over a specific period of time.
Because magnetism is exclusively dependent on magnetic and electrical fields, it is critical to investigate Tungsten conductivity.
Tungsten’s Magnetic Dipole Moment
Because of the presence of unpaired electrons that do not cancel electron and orbital spins equally, tungsten possesses a persistent magnetic dipole moment.
However, in the absence of an external magnetic field, the net dipole moment’s direction is randomly distributed throughout the element, resulting in no or very weak magnetization behaviour.

What’s the difference between ferromagnetism and paramagnetism, and how do you tell the two apart?
The attribute of ferromagnetism is the strong attraction of some elements to a magnet. One of the most common examples is iron.
Paramagnetism, on the other hand, attracts elements to the magnet only weakly.
Only these two properties attract a magnet; superconductor and diamagnetic properties repel it.
What is the definition of a magnetic dipole moment?
Magnetic moment describes the strength of a magnetic field as well as the orientation of an element that generates one.
The magnetic moment is another name for the magnetic dipole moment, which occurs when a magnetic dipole with discrete positive and negative charges stabilises at the north and south poles.
What is the definition of a magnetic field?
The magnetic force on a moving charge or material is determined by this field. Charge travelling through a magnetic field is subjected to a force that is perpendicular to both its velocity and the magnetic field.
Tungsten has a high thermal conductivity.
Tungsten’s heat conductivity diminishes as the magnetic field increases.
A question arises here: what happens if a paramagnet is held in a magnetic field and its magnetization is raised until it becomes constant?
How would the magnetization property of a paramagnet behave if the temperature drops?
Heat is inversely related to a paramagnet’s fluctuating magnetization behaviour, as shown in the graph; the magnetization will rise as the temperature decreases.
There are no constant values in magnetism because both the electrical and magnetic fields influence the electron’s spin, resulting in microscopic fluctuations in values.
Tungsten’s Characteristics
Tungsten has the highest melting point of all metals, at roughly 3420 °C.
At 20 °C, the density of this metal is roughly 19.3 g/cm3.
Tungsten develops a patina on its surface that protects metal from rust caused by the environment. The following is an article about tungsten rusting.
It’s found in a lot of light bulbs including incandescent light bulbs.
Conclusion
Tungsten is a metal that contains no iron, hence it cannot be a ferromagnet. Because tungsten has four unpaired electrons, it is the source of all unexceptional qualities.
One strange occurrence for Tungsten is that it exhibits mild magnetic. Tungsten is naturally paramagnetic, however it can be changed to ferromagnetic by using a strong ferromagnetic element.
To diminish its paramagnetic properties, tungsten can be alloyed with cobalt, iron, or any other strong ferromagnet.
