Magnetic monopoles

You can have magnetic monopoles in theory but can you have them in nature, in plasma cosmologies and in Electric Universe theory?

As a child, James Pinfold adored magnets. He recalls marveling at the invisible force that clacked the metallic objects together or hurled them apart. Out of curiosity, he once sawed a bar magnet in half, trying to separate its north and south poles. Like anyone else who’s ever made the attempt, Pinfold instead just ended up with a pair of smaller two-poled magnets. “I thought, ‘That’s amazing,’ ” says Pinfold, now a physicist at the University of Alberta. “Why could there not be separate poles?”

It’s a question he’s never stopped asking. Pinfold is now the leader of an experiment looking for theoretical particles with single magnetic charges — a north without a south, and vice versa. Called magnetic monopoles, they seem perfectly possible, even inevitable, in a host of theories physicists have proposed for unifying nature’s fundamental forces.

Yet the pesky particles have eluded science’s grasp for decades. Researchers have looked to the skies, in seawater and in ice for them. They’ve picked through rock samples from the Arctic and Antarctica, searched in meteorites and moon dust, and sought traces of them in ores dating back nearly a billion years. In the history of science, arguably nothing has been searched for more, through both space and time, than the magnetic monopole. And still, nothing.

Magnetic monopoles

In Maxwell’s theory, there was only one piece missing for a perfect symmetry between the electric and magnetic forces, the magnetic monopoles. As theoretically demonstrated by Dirac, the existence of this single magnetic monopole would explain quantization of electric charge everywhere in the Universe. Since then, the search of such magnetic monopoles—as real elementary particles or effective quasiparticles—has been a great preoccupation for physicists and it’s of great importance. Their existence or discovery could lead to the unification of the fundamental interactions, another big problem of our century.

Despite the lack of experimental evidence for elementary monopoles in nature, magnetic monopoles can emerge indirectly or mathematically. For example, nuclear rotation of a diatomic molecule can be seen as a charged particle interacting with the field of a magnetic monopole. More recently, it was shown that a magnetic monopole fields could emerge from the angulon, a new quasiparticle concept representing a quantum impurity exchanging orbital angular momentum with a many-particle bath. This angulon serves as a reliable model for the rotation of molecules in superfluids.

Magnetic monopoles

In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). A magnetic monopole would have a net "magnetic charge". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.

Magnetism in bar magnets and electromagnets is not caused by magnetic monopoles, and indeed, there is no known experimental or observational evidence that magnetic monopoles exist. Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.

In classical physics, you will see that every field or interaction is basically communicated by a pole which we call a monopole. We have just mass for the gravitational field and electric charge for the electric field, but when we come to the magnetic field, we find a dipole made up of the South Pole and the North Pole.

Physicists since classical times have not found a single magnetic pole made only of the North Pole or the South Pole (shown in the featured image). These two poles are always together to create the magnetic field.

In classical physics, we are taught that a moving electric charge creates a magnetic field, so physicists are assuming that if we can find a magnetic monopole or what we can call a magnetic charge, then it could become possible to observe a moving magnetic charge create an electric field. This asymmetry between the electric field and the magnetic field has been noticed since classical physics especially when Maxwell’s equations do not reflect any symmetry between both fields.

The search for magnetic monopoles has become a major undertaken in physics because of its recent prediction by certain grand unified theories and also by string theory, but till today no magnetic monopole has been discovered.

However, now that we have post-modern physics, what does it say about the existence of magnetic monopoles. Do they exist according to post-modern physics? Well, if you have been studying post-modern physics, as I have begun to teach it on this great science blog, then you should know what post-modern physics thinks about the existence of magnetic monopoles.

It first begins with the fact that in post-modern physics, there are no such things as a separate electric field and a separate magnetic field. What causes a free electrical body to move or translate is the electromagnetic field and what causes the electrons in the magnet to spin is the electromagnetic field.

Gauss’ Law for Magnetism states that “the total magnetic flux out of a closed surface is zero”. Unlike electric flux which originates and terminates on charges, the lines of magnetic flux are closed curves with no starting point or termination point. This is a consequence of the definition of magnetic field strength, H, as resulting from a current (see Ampere’s Law, below), and the definition of the force field associated with H as the magnetic flux density B = μH in teslas (T) or newtons per amp meter (N/Am).

Therefore all magnetic flux lines entering a region via a closed surface must leave the region elsewhere on the same surface. A region cannot have any sources or sinks. This is equivalent to stating that magnetic monopoles do not exist.
