Sorry I did not explain well. I Attached a picture of a stator for magnet AC alternator from windbluepower.com. There are two layers of ring coils. Based on the previous answer, the reason it has two layers becasue of space limited when a rotor spinning around the coils? or something...

Assuming the rate of a magnet moving and the size of the coils are the same. the coil is 1 in diameter and the inner diameter is 1/2 in a cylinder magnet diameter 1/2 inch and 1/2 thick. case 1: place 2 coils next to other. a magnet passing by say 1/2 inch apart. case 2: same as case 1...

Not really. I would like to understand the relationship between magnets, and magnetic fields. For example does the characteristics of magnet changes, fields changes in this case if any.

I am very bad at drawing. Imagine 2 magnets, places on the same line facing east, both N poles also facing east, 3 inches apart, magnet 1 behind magnet 2, . Both magnets start attracting each other when near together say 2 ins. 1. shield the S pole of magnet 1. Just using shield...

My "application" is flying right throght the trash can after reading your reply(:- Let me try to understand the basic here... ex: magnet 1 shield around S pole, the N pole shield around like a pipe and redirect to target magnet 2, S pole. Magnet 1 eventually will die out?? and what happen...

First I am sorry if this question is not quite related to this forum. But I have not where to go So I just post it here hopfully one can help. Thanks in advance. I have two strong magnets. Each has around BrMax: 13200 gauss and pull force 27 lbs. I am looking for a magnetic shield...

Thank you. Now, If I have two coils and 1 magnet. If a magnet pass through between two coils, I will get two powers on two coils (1 through the N pole and the other to the S pole). case 1: If two coils connect in series, I would get not thing because N and S cancel each other. case 2...

Dave, According to Faraday's law if turns increase, V will increase. But Current should be reduce due to the coil increasing load (resitent). I think! Otherwise, we would have infinite output just by increasing turns! I could not find the current formula. It would be great if one can...

Am I understand correct that when an air coil pass through magnetic flux, it create current and emf? power = IV If turns increase, do I get more power? why? If power changes, then how to get out max power.
