A new study develops a theory of how magnetic switchbacks are formed around the sun. This quantitative model can be used to predict magnetic field variations and potentially explain the heating and ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

Reconnection, the merging of magnetic field lines of opposite polarity near the surface of the sun, Earth and some black holes, is believed to be the root cause of many spectacular astronomical events ...

As stellarator configurations are challenging to build, most fusion experiments today are tokamaks (a short form for a Russian expression that translates as ‘toroidal chamber with magnetic coils’).

HANOVER, N.H. – April 28, 2022 – When magnetic field lines of opposite directions merge, they create explosions that can release massive amounts of energy. On the sun, the merging of opposing field ...

Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered one-half of the planet? This is what a recent study published in Geophysical ...

These are gigantic masses of material, directly affecting the magnetic field. They’re called Large Low-Velocity Provinces ...
