What Is The Force Of The Magnet's Magnetic Force
Aug 09, 2018

The electromagnetic force, strong and weak force are very small, the strength is about 10 minus 15 square meters, the weak force is 10 minus 18 square meters. Therefore, these two forces will not have macro performance.

There are two gravitational and electromagnetic forces left. The strength of gravity is 10 minus 39 times the electromagnetic force. It needs a huge mass to be more obvious. The electromagnetic force is different. Its strength is strong and the force is far. It is common in daily life. Sources of force, such as pressure, friction, tension, etc., are caused by electromagnetic interactions.
