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.
