WebApr 8, 2024 · Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space. This magnetic field is known as the ... WebSep 1, 2005 · Electric Field The electric field is defined as the force acting on a positive test charge, per unit charge. 0 0 q 0 points in direction of q ≡> F EEF Units are thus N/C for the electric field. It is similar to the gravitational field on the surface of the Earth for a test mass m0: m0 = F g The electric field is a vector field.
