One of the most basic properties of magnetism is that a magnet always has two poles, north and south, which cannot be separated into isolated poles, i.e. magnetic monopoles. There are strong theoretical arguments why magnetic monopoles should exist, but in spite of extensive searches they have never been found. This article gives an introduction to theoretical and experimental aspects of magnetic monopoles and discusses their role in our understanding of fundamental physics, both historically…

TLDR
The role of magnetic monopoles in quantum field theory is reviewed and their implications for particle physics and cosmology are discussed.
Status of Searches for Magnetic Monopoles
Searches for magnetic monopoles (s) are a fascinating interdisciplinary area with implications for fundamental theories, particle physics, astrophysics, and cosmology. The quantum theory of s, and
Magnetic monopole creation
Elementary magnetic monopoles have never been experimentally observed but there are credible theoretical reasons to believe that they may nonetheless exist. This thesis gives partial answers to the

The possible existence of “magnetic charge” has been widely investigated in the last two centuries, since it would allow to symmetrise Maxwell's equations and to explain charge quantization. Though,
Searches for Magnetic Monopoles: A Review
This report briefly reviews selected searches for magnetic monopoles. The theoretical motivation behind their existence is highlighted. The focus is on the results of the searches and the bounds set

TLDR
The bounds on monopole masses arising from the strongest magnetic fields in the universe, which are in neutron stars known as magnetars and in heavy ion collision experiments such as lead–lead collisions carried out in November 2018 in the large Hadron collider at CERN are discussed.
Magnetic Monopole Cannot Be Incorporated into the Dual Framework of Electromagnetic Theory
Through reexamining the intention of duality in classical physics, we will develop the electromagnetic field equations (EFEs) into a new dualized form. In the process, we will see 1) the dual
Searches for magnetic monopoles with IceCube
Particles that carry a magnetic monopole charge are proposed by various theories which go beyond the Standard Model of particle physics. The expected mass of magnetic monopoles varies depending on
Radiation arrow and missing magnetic monopoles
In this paper a new solution for the time-asymmetry of radiation is proposed. The novelty is that the time behaviour of the electromagnetic field is unlinked from the time behaviour of the charge in

Theoretical and experimental status of magnetic monopoles
The Tevatron has inspired new interest in the subject of magnetic monopoles. First there was the 1998 D0 limit on the virtual production of monopoles, based on the theory of Ginzburg and
Magnetic monopoles
A solitary, uncorroborated event at Stanford is the only evidence that magnetic monopoles might exist. Powerful theoretical motivation for monopoles derives from Dirac's assertion that monopoles
Search for magnetic monopoles
Attempts are described to detect particles having a monopole magnetic charge. Theory predicts for this particle a charge of l37/2e, a mass of about 2.4 Bev, and a production cross section of greater

TLDR
The overall monopole/nucleon ratio in the samples is <1.2 \times 10^{-29}$ with a 90\% confidence level, and the overall monopoles in matter is found to be zero.

Thermal fluctuations of the gauge field lead to monopole formation at the grand unified phase transition in the early Universe, even if the transition is merely a smooth crossover. The dependence of
