Why is EMC? Not "electric" or "magnetic"? Electricity and magnetism in physics tell us that electricity and magnetism can be converted under certain conditions! (magnetic generator, magnetic motor) is called electromagnetic compatibility!
Why "compatible"“
Since we understand why EMC is called "electromagnetic compatibility", it is not too difficult to understand the word "compatibility"! At large, the earth is a big magnetic field, and every electronic device will be affected by it; at small, every electronic device is a "magnet". When they exist in a relatively small place at the same time, they can not affect each other and cause abnormal functions!
