Visualize the magnetic field generated by a current-carrying loop using Python simulation. This video demonstrates how electric current creates magnetic field lines, making core electromagnetism ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

A new video shows how Earth's magnetic field weakened and warped before temporarily flipping during a recent "polar reversal event." When you purchase through links on our site, we may earn an ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...
