Earthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.The field then creates the magnetosphere, which acts sort of like a force field, protecting the planet from the brunt of the sun's solar wind.arthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.
Earth's magnetic field protects us from the solar wind. Image credit: NASA. A magnetic field is the area of influence exerted by a magnetic force. This field is normally focused along two poles. These poles are usually designated as north and south.However these directions are not the only two that a magnetic field can have.arth's magnetic field protects us from the solar wind.
