The Sun’s activity is determined by the Sun’s magnetic field. Two combined effects are responsible for the latter: The omega and the alpha effect. Exactly where and how the alpha effect originates is ...

The magnetic field of the Sun is generated by a dynamo effect caused by its convective and rotational movements. It will ...

The generation of the magnetic field on Earth made scientists wonder if the process occurred in the earliest days of the planet. The magnetic field generation was explained by a mechanism known as the ...

Magnetars are a class of neutron stars with the strongest magnetic fields in the Universe. These incredibly dense objects are central in the landscape of extreme phenomena such as hypernovae, fast ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
