Magnetosphere Formation of A Tidally Locked Planet or Satellite

Deepanshu Chouhan

Magnetosphere is the part of a planet that contains the magnetic field lines that prevent harmful solar winds that can wipe out any kind of life by destroying the atmosphere of the planet. Some tidally locked planets were thought to lack this magnetosphere as they don’t have convection currents in their core, but recent studies of exo-planets have revealed that due to tidal heating, core of planets can melt. If the temperature inside the core excides a certain threshold then due to ionization the core can get partially charged producing a changing electric field which in turn can produce magnetic field.
