gravitational field - a field of force surrounding a body of finite mass. field of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it.
geomagnetic field. The magnetic field of the earth which drifts over time. It is created by electrical forces that are formed by the movement of the molten metals in the outer core. Is different from the magnetic field of a bar magnet.n space the area that surrounds the Earth & contains Earth's geomagnetic field The area surrounding Earth that contains Earth's magnetic field & is created by the interaction of Earth's magnetic field with gases from the Sun. It also keeps Earth from receiving too much energy from the Sun. î î î.
