At the north and south poles
the magnetic field lines converge, the Earth drags the atmosphere around a single point, the tropopause is lower, and temperature inversions are common.
The neutron star's
magnetic field lines converge at the magnetic poles, so the charges get focussed and a narrow cone of non-thermal radiation is beamed outward.
These form in areas where
magnetic field lines converge, producing cooler regions of «only» about 3,000 — 4,000 degrees Celsius (by contrast with their surroundings of 5,000 degrees Celsius or higher).

magnetic fields, or basically everything in the radiation belt environment, including the electrons, which descend following Earth's
magnetic field lines that
converge at the poles.
Particles, including electrons, in the solar outburst can penetrate the ionosphere, following Earth's
magnetic field lines, which
converge at the poles.
The current travels along
magnetic field lines which
converge in a circle around the poles.
