In 1916, the Einstein theory of general relativity opened a new era in physics. However, Newton’s theory is sufficiently accurate enough to be used in low gravity phenomena. Its solutions notably deviate from the absolute values, when it is used to solve high gravity problems. Newton’s theory of gravitation isn’t a very accurate universal theory. However, in the 20 th century, some astronomical phenomena were observed that cannot be explained using the Newton’s theory of gravitation. Newton thought that his theory was a universal theory which could be used to explain any gravitational interaction in the universe. This is usually expressed as F = GMm/r 2 where F is the gravitational force, G is the universal gravitational constant, r is the distance between the two objects, and M and m are the masses of the two objects. According to his theory, the gravitational force exerted on an object due to mutual interaction with another object is directly proportional to the product of two masses and inversely proportional to the square of the distance between the two objects. His theory is commonly referred to as “the Newton’s theory of gravitation” which states that every object with a mass attracts every other object through the gravitational force. Eventually, great English scientist sir Isaac Newton developed a very successful theory of gravity. Gravity isn’t a new concept Several scientists and philosophers including Galileo Galilei and Aristotle attempted to explain and study the gravity. In modern physics, gravity or gravitational interaction is one of the four fundamental interactions. This article attempts to give you a better understanding of those differences. There are many other differences between gravity and magnetism. However, magnetism is a special property of moving charged particles and magnetic materials. Gravity is a common property of both matter and anti-matter. The main difference between gravity and magnetism is that gravity is a consequence of space-time curvature caused by mass whereas magnetism is produced by moving charged particles or some materials. In magnetism, both attractive and repulsive interactions are possible. Gravity is always an attractive interaction. Magnetism is a very strong interaction compared to gravity, which is the weakest interaction. Gravity and magnetism are two types of fundamental interactions in nature.
