Magnet Myths and Misconceptions

[tinman]

Brad, remember my post explaining why you had the most induction when your pancake coil was in the middle? If not, perhaps review it.

The magnetic field of the magnet is not the strongest at the middle, in fact it is the same all along from end to end. But at the center, there is a maximum NET flux that can be intercepted by your coil, provided the coil encircles the magnet as you have shown.

Yes,i read the post Poynt.
Please see post 485 and486.
Why wont this area of maximum net flux make it's way through inductor B?,when either side A&C with less flux area will induce it's flux into the core of inductors A and C,and thus cause a current to flow-in opposite directions mind you.

Two reasons:

1) In the middle, most of the flux is confined within the magnet itself.

2) While swiping across the middle area, you are inducing as much positive voltage as you are negative, so what is the result?

Like i said before Mark,your compass experiment is flawed. Now how about you try your own experiment,and let us know the result's of my test.
You take two bar magnets,and you face the north of one end of one magnet to the south end of the other magnet. You now place a 1/2 inch plastic spacer inbetween those two magnet,so as you have(N-spacer-S). Now you know that there is a north and a south field there(im useing north and south-as that's what were taught in school,and we all know how much you like sticking to what we are taught)-->now try your own test. As you will know without even trying the test,the results will be exactly the same as the test you wish us to carry out.
Like i said,your compass test is flawed,and of no use to this thread.

Why do you think there is a flaw?  Unless you use a big compass, or get really sloppy you will be able to map the composite contour.

Tinman - I concur! My Experiments agree! In-fact B will be repelled from its position there at the Bloch Wall!

Kind Regards

LOL!  You think that in a stack of end to end high energy magnets that one of the adjacent N-S aligned magnets will repel?  You could easily lose a finger with such a loopy belief.

Really - Simple questions give answers!


Why is there a Concave at the Bloch Wall and not Convex? This fact is exaggerated with Longer Magnets! I know MarkE's answer but for others - Why

You keep claiming that there is a Bloch wall where there is none and no evidence for one.   This put on act of yours is nuts.
