The density of electric field lines represents the strength of the electric field in a given region. A higher density of electric field lines indicates a stronger electric field, whereas a lower density indicates a weaker field. This provides a visual representation of how the electric field intensity varies in space.
Field name and Data type
The presence of a magnetic field indicates that a planet may have a liquid outer core made of iron and nickel. This liquid outer core generates the planet's magnetic field through a process called dynamo action. The magnetic field helps protect the planet from solar wind and cosmic radiation.
