The gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, g of Earth is equal to the acceleration of free fall at its surface, 9.81ms − 2.

If the Earth were to lose its magnetic field, things would get a lot more interesting. We'd get a lot more ionizing radiation at the surface, which would result in more mutations (and more deaths).
The equator is the center of the earth's surface which is an equal distance from each pole. The poles are points on both sides of the earth which supposedly create the magnetic field around the earth.
The Most Energetic Cosmic Rays Are Dangerous Because They Are Ionising Radiation. Fortunately, On Earth We Have Two Very Effective Line Of Defence: The Earths Magnetic Field And Its Atmosphere! x
the magnetic field of a magnet is measured through Gaussmeters.
I assume you mean, of the gravitational field? The gravitational field is inversely proportional to the square of the distance. At a distance of 1 Earth radius, the distance from the center of the Earth is twice the distance at the Earth's surface; thus, the field strength is 1/4 what it is on the surface. If at the surface the field strength is about 9.8 meters per second square, divide that by 4 to get the field strength at a distance of one Earth radius from the surface.I assume you mean, of the gravitational field?

Mercury's surface gravitational field strength is 0.38 times the Earth's.
Potential energy
Not very strong in comparison with a typical small "bar magnet" which has a field strength of roughly 100 gauss. Earth's magnetic field strength at the surface is about 0.3 to 0.6 gauss. That's stronger than some planets and weaker than others.
The acceleration due to gravity on the surface Venus is 8.9m/s2 That's about 90% of Earth's.
The further away from the Earth's surface you travel - the weaker the gravitational pull is.

Earth's magnetic field strength at the equator is about 30 microtesla.
A conductor that is directly connected to the earth is called ground. One of its applications is through the determination of the field strength of surface wave radio transmissions.
Newton's definition of gravitational force, F=Gm1m2/r2. G = 6.6742(10) x 10-11 m3 kg-1 s-2 or N m2 kg-2.The SI unit for gravitational field strength is G.
9.8 N/kg is the gravitational field strength on Earth, meaning that for every kilogram of mass, there is a force of 9.8 Newtons pulling the mass towards the Earth. This value is commonly referred to as the acceleration due to gravity.
The surface gravity of Uranus is similar in strength to Earth's. It depends on exactly how you measure it and how you define it. Some sources put it at about 90% of Earth's, others say it's up to 115% of Earth's.
