Summary
Colloidal particles heated or cooled in specific solvents exhibit electric/magnetic monopole-like fields, challenging previous assumptions. Numerical simulations confirm these fields, though particles do not fully behave as true monopoles.
Area of Science:
- Non-equilibrium thermodynamics
- Soft matter physics
- Computational physics
Background:
- Electric charges are conserved, and magnetic monopoles have never been observed.
- Non-equilibrium thermodynamics and Maxwell's equations suggest colloidal particles may exhibit unusual charge-like behavior.
- Previous studies lacked definitive numerical evidence for monopole-like fields in such systems.
Purpose of the Study:
- To investigate the behavior of heated/cooled colloidal particles in polar or paramagnetic solvents.
- To numerically simulate and analyze the field distribution around these colloidal particles.
- To compare the simulated fields with theoretical predictions for electric or magnetic monopoles.
Main Methods:
- Numerical simulations of colloidal particle systems.
- Analysis of field distributions around heated/cooled colloidal particles.
- Comparison with theoretical models of electric and magnetic monopoles.
Main Results:
- Simulations show field distributions around colloidal particles quantitatively match theoretical predictions for oppositely charged electric or magnetic monopoles.
- Non-equilibrium colloidal particles do not exhibit all characteristics of true monopoles, such as response to homogeneous fields.
- Numerical evidence supports the existence of monopole-like fields.
Conclusions:
- Heated/cooled colloidal particles can generate monopole-like fields, providing crucial numerical evidence.
- These findings advance our understanding of non-equilibrium thermodynamics in soft matter systems.
- Further research is needed to fully characterize these phenomena and their implications, distinguishing them from effects like thermophoresis.

3.1K
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...

Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets....

A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.

Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.

Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

3.4K
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...
