ANSWER: There is no valid reason. The important thing is the fact there are two categories of electronic fees (in the place of gravitational bulk wherein there is certainly seem to only one type) and is smoother in order to name you to definitely confident and another negative. The convenience is within the mathematics; age.g., in the event your push anywhere between a few confident charge are repulsive, upcoming therefore is the push between a couple negative fees given that push utilizes this product of charges. In addition, it actually was Benjamin Franklin who to start with branded the brand new the type of charges and this electrons are actually as bad (electrons had not been seen myself in his day).
I remove him or her independently for a few grounds
ANSWER: In a way one to magnetism is what is when you place energy inside the action. You are best we should not reduce power and you will magnetism since the one or two something different because they are most one another components of electromagnetism. First, this was the fresh historic development and contains thus getting seriously inserted throughout the vocabulary out of physics. Next, the fresh new relevant phenomena are a lot simpler to understand statistically when we speak about these vectors; a proper and you may strict answer to explore electromagnetism is to apply what’s known as electromagnetic job tensor, a single statistical entity, but a beneficial tensor try a more difficult concept to know. Continue reading All of the math out-of stamina and you will magnetism could well be just the exact same when we titled electrons positive
