Can an exterior magnetic field be created using permanent magnet induction?

Click For Summary
The discussion centers on creating an exterior magnetic field using a setup involving a rotating neodymium magnet in a Halbach Array and a closed loop coil. The main goal is to induce electron flow in the coil by producing a changing magnetic field, as a constant field will not suffice. Participants express skepticism about the feasibility of generating a significant external magnetic field due to the nature of toroidal and solenoidal configurations, which typically produce negligible external fields. The original poster aims to utilize the induced magnetic field for applications in non-destructive testing and therapeutic devices, but doubts arise regarding the effectiveness of the proposed design. Overall, the feasibility of achieving the desired magnetic effects remains uncertain.

I have found that it's much easyer to have the magnets do the moving. When you have the wire moving, the electrical connections needs to be adapted to alllow for that movement in one form or another and that ads more parts. If you have the magnets do the moving the wire can be stationary and a direct connection can then be realized.

but i can't get a way through this,
what if i do rotate the coil and magnet one by one,
how will my experimental setup look like?
i at sea with this:S

Nanobot, I must tell you that, The original post was a question about creating an exterior magnetic field around, what I now call a spherical coil. I can advise you in-regards to what I found is easyer to do. ie: move the magnets or move the wires. In my project both the magnet array is moving but the wire has limited movement.

I'm not able to design what your thinking because I just don't know what your out come should look like or how any of the parts relate to each other.

I would prefer if you stay in-keeping with the original post or post your question in the forum and have some one that has some more exprience in answering it.

Thanks
