... Note: sketch means sketch - just a rough plot which shows key features (e.g. what's it do near the origin? Near infinity?) We don't want to just calculate E fields; we want to be able to imagine what they look like, so sketching fields is important. (You can always use a program (like Mathematica) t ...

When do particles follow field lines?
... the question posed in the title by seeking to provide at least partial clarification of the question of whether, and in what way, particles ‘‘follow field lines’’ or behave like ‘‘beads on a string’’ in certain limits of perpendicular diffusion. We shall do this by presenting results from numerical ...

The origins of electrical resistivity in magnetic reconnection:
... The essence of the simulation results with an applied magnetic field is briefly described. Figure 2 is the time snapshots of the poloidal flux function (Tanaka, 1995b) defined by B p = ∇ × ( ŷ), for the times t/τ A = 0.75, 1.9 and 2.5, where τ A = 12 d/V A with d the initial separation of the fl ...

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.
