C. METAL CORE
The inner core of our earth, where the metal core is found, produces gravitational waves and creates what's called the magnetic field.
Although according to Chris Phillips, a retired lecturer, the magnetic field does not take into account the Solar Wind. If we think of the moving charged particles ‘blowing’ through our planet then a supplementary source of electricity arises. Electric current generates magnetic fields so maybe there is an additional source for our ‘invisible protector'.
