The first solution to the Yang-Mills field equations with a vector potential proportional to one over r was an example of this.
An object like one of these things creates a geometric pattern on the surface of superfluid helium-3 called a boojum. The first solution to the Yang-Mills field equations with a vector potential proportional to one over r was an example of this. These things are equivalent to dyons with (*) zero electric charge. According to the Dirac quantization condition, this particle implies that all electric charge is universally quantized as a multiple of two pi. Along with the flatness  and horizon problem, cosmic inflation was posed to solve the problem of the low abundance of these things. If this particle were to exist, then the divergence of a magnetic field would be nonzero.  For 10 points, name this hypothetical elementary particle whose existence would violate Gauss's law of magnetism.
