Question about electricity and magnets

Mates,

I am trying to learn a little more about the concepts I see so often. I was hoping for a shortcut to an answer to the following question since it related to guitars.

Here is my present assumptions and question, which I list in case my assumptions are wrong

- a guitar uses permanent (d/c) magnets,

- the concept of impedance has the components of both magnitude and phase when referring to a/c current, but only magnitude when referring to d/c current

So why do we have "out of phase" wiring for pickups? Doesn't the d/c magnetic field only circulate to the right?

Thanks for any guidance

Interesting questions, and I think we can all benefit from a good explanation.
Also the difference between reversed polarity and actually flipping the magnets in a pickup.
This article explains the reversed polarity aspect, but does not touch on the magnet flipping thing.

A student was being interviewed for an electronics course at a university.
"So tell me", said the prof. "What IS electricity?"
The student stammered for a moment then said, "I'm sorry professor. I do know, but I have forgotten"
"That's a tragedy", said the prof. "Two people in the universe know what electricity is, you and the almighty. And now one of those two has forgotten".

It's the same for magnets. But as to your question, yes sort of. The magnet provides some bias to the coil so it has something to work against. The clock/anti clock thing has to do with the direction of magnetic field caused by the current in the coil. You can work out which way it should go from first principles, but it is a lot easier to suck it and see. Then turn the magnet round if it comes out backwards.
 
Yes, but after all that, if one flushes the toilet in the Northern Hemisphere, the water swirls down the opposite way than it does below the equator.

Oh, and don't ask how I know what happens if you pee on an electric fence.

Thank you for the very helpful explanation. Unfortunately, the above activity exceeds what I am willing to do to advance my knowledge.
 
I was positive I could find an answer to this question.
I have looked both north and south to find an answer
but my results were on the negative side of the scale.
I was shocked that I couldn't find the information.
I don't know watt to do to help you.

Sorry.
 
Did you know? The earth's north magnetic Pole, buried up there north of Greenland, beyond the Canadian Tundra and past Svalbard, the Kingdom of the Ice Bear is in fact a magnetic south pole. Makes you want to kick the dog.
