The Earth's gravitational force, which takes place on the body mass of a body near the surface of the Earth, is called the gravity of the Earth. g is denoted as. If a body is moving independently in the absence of any force other than the force of gravity near the surface of the earth, its acceleration is equal to g. Its value is approximately 9.81 m / s2. (Keep in mind that G is different; it is a gravitational determinant.) The value of g varies from place to earth.The gravity-traction of the Earth is much less than the sun's gravity. And due to the gravity-traction of the sun, our earth continues orbiting in its own chamber. From which we get to see the night and day. Gravitational traction has kept the atmosphere of life and human life close to us. Through which we can breathe in the form of oxygen. And water and other things can be stable on the earth's surface by gravity-traction.Because of this, there is the burden of every living being and non-living. And due to the gravitational traction of the moon, tides come in the ocean. Even when we burn a flashlight in the sky, due to the pull of gravity-traction, light of torch shines in red light. Although it is difficult to see the naked eye, but the scientist can easily measure it. Gravity-traction on the earth is more or less than the space-place. Wherever the Earth has less land mass, there is more gravity-traction. And where the mass of the earth is less in the earth, there is less gravity-traction.The solar wind, the Earth's magnetic field and the upper atmosphere make Melaar Aurora. The magnetic pole of the Earth keeps moving from these irregularities to all these factors, and sometimes it also gets reversed. The earth's magnetic field and the solar wind milkar van Anderson radiation leash, which is a pair of donuts shaped rings made of plasma, which is in the ring of the four corners of the earth. The outer lease is from 19,000 to 41,000 km, whereas the strap is 13,000 km to 7600 km.The big disturbances occurring in the Earth's magnetic field are called a magnetic storm. The intensity of magnetic storms is highest in areas of polar light. It appears that expelled from the Sun, magnetic storms originate from streams or clouds of ionized gases, which reach the Earth. Irregular or transient magnetic changes occur on the occasions of unusual sun spots. There are many types of magnetometer for measurement. Absolute magnetism is based on the known field of electrification in a horoscope and comparisons of the geomagnetic field. Variable motivation is a secondary device and makes relative measurements. Fluxgate magnetometer and proton magnetometer are more subtle.
