then type in your questions one by one. and search the results for your answers.
Everytime you have a new question, either create a new window and type in that other question or save your question until you finish reading your current answer and then go back to the search page and type in the question.

A single book alone will not suffice to answer all questions about electronics.
like how to set the "phase" of a magnet? and why is it 180 degrees only i want to get like 20 degrees, or 60 degrees or 135 degrees how do i get that with a magnet?
I don't think your problem is getting the answers, i think its asking the right questions.
For example you ask "what sets a magnet's phase?" this is not a proper question without the right context.
A magnet is a piece of material with a magnetic field. While phase can have many meanings from the physical state of matter (say liquid, solid or gas) to the displacement of a waveform in time.
you need to ask the question and include the right context. it would make much more sense to ask "what is the phase of the magnetic field in relation to a brushless DC motor?" then we would get somewhere, and you can then go into google and find out.
Lack of a proper question will almost always lead you to an improper answer. Like if i asked "Why is paper black?" you might answer "paper is not black, or if it is, it is because ink was spilled on it." This is not the proper answer because the context of the question is: "Why is burnt paper black?" now you can give a much more direct answer.
Google cannot answer questions that are not properly asked. It is a computer program, not a person.
When i wrap a coil of wire around the magnet from S to N its in phase zero degrees when i wrap the coil of wire the other way N to S its out of phase 180 degrees
How do i get in between phase degrees?
like 20,40,60,80,100,120,140, phase degree?
I think phase is a state of matter, like a liquid phase, or a solid phase. In biology phase is about the current cycle of a cycle, telephase, interphase and whatnot...
I have a guitar pickup and a guitar pickup is a coil and a magnet with 2 wires the hot and ground . One way its inphase zero degrees flip the wires around the guitar pickup is out of phase 180 degrees. The guitar outputs current and voltage 100mv or so with load. How can i get the guitar pickup to go 20,40,60,80,100,120,140, phase degree?
The hot and ground wire from the pickup only have 2 options zero degrees and 180 degrees its because of the magnet can get inbetween
20,40,60,80,100,120,140, phase degree?
instead of breaking your guitar to change the pickup coil properties, wouldnt it be easier just to add something after the pickup output to change its phase?
Why change the phase of the pickup? You can't hear actual phase. Phase shift is measured from a reference but a guitar pickup doesn't have a reference phase.
Walters, I think it's time for you to get a basic book on electromagnetic theory and practice and a book on basic transducer theory and spend some time with them. You're not asking for a little clarification of some fine points of electromagnetic theory or transducer design, you are asking for respondants to conduct a class on electromagnetic theory. That's fine as long as everybody is happy to keep involved, but it doesn't look like you are bringing a foundation in electromagnetic theory to the discussion that allows you to understand the responses. This thread looks like someone trying to explain color to a blind man.
I'm tempted at this point to get into an explanation of why you cannot get any arbitrary phase out of the variable reluctance transducer formed by the magnet, coil, and guitar string (although you can do phase-shifting in circuitry external to the transducer), but I'm going to resist and urge you to hit the books.
Please don't take offense at this comment. It is intended to guide you, not insult you.
Its ok to help, but not when you throw 1,000 random questions, because no one can answer 1,000 random questions in detail, and it would be useless taking them in, when you only need one major question answered. right?
and isn't your question supposed to be something like:
I want to experiment with magnets but I know nothing about them. Where do I start?
