Hello everyone, I was wondering which field of study teaches how to make electronic components. For example, I would like to learn how to make resistors, caps, led, transistors... I have more or less of the theory, such as what the Dirac gaps are, if we talk about semiconductor... But what I...

No, as long as it has an electric charge, it will always have an electric field. Remember, motion is relative, so although your electron is moving, it is always at rest with respect to itself. The only reason they don't talk about it when introducing magnetism is the equation gets complicated...

I thought I understood it cause I always had the right answer ever since I learned about it. But now my friend asked me a question about why does a piece of chalk break if you put a heavy thing on it, say a car. If we just think about action and reaction, the forces have to be along a...
