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.
It does seem clear that the generation of the magnetic field is linked to the rotation of the earth, since Venus with a similar iron-core composition but a 243 Earth-day rotation period does not have a measurable magnetic field.
