At mid latitudes, one or a few base stations are typically located within or near the survey area and are used to monitor and remove time dependent variations. These are usually assumed to be of external origin and uniform throughout ...

Spin-dependent magnetic focusing Yuli Lyanda-Geller and L. P. Rokhinson Stefano Chesi
... Magnetic focusing manifests itself as equidistant peaks in magnetoresistance R(B⊥ ) for only one direction of B⊥ . R is measured by applying small current through the injector QPC while monitoring voltage across the detector QPC. At B⊥ < 0 cyclotron motion forces carriers away from the detector. Tha ...

Lesson 18 (1) Force on a Current Loop in a Uniform Magnetic field
... (5) Energy of a Current Loop in a Magnetic Field This energy is calculated from the work required to rotate the current loop. For that we first need the expression for the work done by a torque on an object. For simplicity, let the object be a rod of length L , and a force F acts perpendicularly to ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, 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 does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
