Magnetic Monopoles - Caltech Particle Theory
... monopoles around today must have been produced in the very early universe, when higher energies were available. Thus, the abundance of magnetic monopoles is a cosmological issue (7-9). In fact, estimates based on the standard cosmological scenario indicate that the monopole abundance should exceed b ...

Modeling the response of thin superconductors to applied magnetic
... With the present work we aim at studying some of the still unsolved problems and at lling a few of these remaining gaps. To do so we extend the Magnetic Energy Minimization (MEM) model, used in previously published studies, to account for the applied transport current and other elements within the s ...

Abstract Magnetic Fields Around Black Holes
... Observations reveal the presence of small regions of space appearing point-like to all current observatories from which enormous quantities of energy are emitted. The most energetic of these objects reside at the center of galaxies and sometimes outshine the rest of the galaxy by up to three orders ...

Magnetic field
A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter (symbol: A·m−1 or A/m) in the SI. B is measured in teslas (symbol:T) and newtons per meter per ampere (symbol: N·m−1·A−1 or N/(m·A)) in the SI. B is most commonly defined in terms of the Lorentz force it exerts on moving electric charges.Magnetic fields can be produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin. In special relativity, electric and magnetic fields are two interrelated aspects of a single object, called the electromagnetic tensor; the split of this tensor into electric and magnetic fields depends on the relative velocity of the observer and charge. In quantum physics, the electromagnetic field is quantized and electromagnetic interactions result from the exchange of photons.In everyday life, magnetic fields are most often encountered as a force created by permanent magnets, which pull on ferromagnetic materials such as iron, cobalt, or nickel, and attract or repel other magnets. Magnetic fields are widely used throughout modern technology, particularly in electrical engineering and electromechanics. The Earth produces its own magnetic field, which is important in navigation, and it shields the Earth's atmosphere from solar wind. Rotating magnetic fields are used in both electric motors and generators. Magnetic forces give information about the charge carriers in a material through the Hall effect. The interaction of magnetic fields in electric devices such as transformers is studied in the discipline of magnetic circuits.
