Electric and Magnetic Tuning Between the Trivial and Topological Phases
... To investigate the nature of the two gapped regions, we perform magnetoresistance measurements in perpendicular magnetic field (Bz ) at the indicated points along lines L and R shown in Fig. 2(a). For clarity, five out of the seventeen measured Hall traces are shown in Figs. 3(a) and 3(b), for lines ...

Induction and Inductance
... 30-5 Self-Induction If two coils — which we can now call inductors — are near each other, a current i in one coil produces a magnetic flux ΦB through the second coil. We have seen that if we change this flux by changing the current, an induced emf appears in the second coil according to Faraday’s l ...

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.
