An electric field is a model which is used to explain influences and behaviors of charges and varying magnetic fields. Electric fields are produced by stationary charge particles and varying magnetic fields. So, neutral particles cannot create electric fields. A gravitational field, on the other hand, is a model which is used to explain. In general relativity, it is well known that, an electromagnetic field can be a source to produce a gravitational field. It was presented that the gravitational field produced from electromagnetic field can be used for space propulsion,. However, the produced gravitational field is very little A gravitational field is a field induced by any object with mass, which will interact with other massive objects by applying a force on it. Gravitational fields are expressed in Newtons per kilogram (N/kg), which is the same unit as acceleration.This means that any massive object present in another's gravitational field will accelerate towards it, and vice versa

Technically, a gravitational field extends outwards infinitely, so the word size does not have much use. You could easily calculate a bodies effective gravitational field (i.e. how far does its gravitational field extend where it is the primary force on objects within it), but this would require a stronger definition of the 'effective' field Any asymmetry in the gravity field is attributed to differential rotation and deep atmospheric flows.

Gravitational field is a concept and a method for calculating and explaining phenomena happening around any object with a mass. A gravitational field is defined around any mass. According to Newton's universal law of gravitation, two masses M and m divided by a finite distance r exerts a force F = G M m / r 2 on each other Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light
Anti-gravity (also known as non-gravitational field) is a hypothetical phenomenon of creating a place or object that is free from the force of gravity.It does not refer to the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift.Anti-gravity is a recurring concept in science. Gravitational energy is the movement of an object or mass that is caused by the pull of gravity. This is caused on Earth by the strong attraction of all other masses to be drawn back to Earth's center. An example of gravitational energy is water from a river tumbling over a cliff to form a waterfall. When an object is lifted from the ground.

You can break down the Riemann curvature tensor into smaller parts The strength of a gravitational field, g, is the force per unit mass on a small test mass placed in that field.The test mass needs to be small because otherwise it will have an effect on the larger mass itself and would therefore alter the value for g. g is also known as the 'acceleration due to gravity' because (when there are no external forces) any object will accelerate towards the.
