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

Click For Summary
SUMMARY

The discussion centers on creating an exterior magnetic field using a neodymium permanent magnet setup in a Halbach Array configuration. The user aims to induce electron flow in a closed loop coil by generating a changing magnetic field, as a constant rotating field will not suffice. Participants clarify that while the Halbach Array can enhance the magnetic field on one side, the external field produced will be minimal due to the nature of toroidal solenoids and the opposing forces generated by the coil windings. The consensus indicates that achieving a significant external magnetic field with the proposed design is unlikely.

PREREQUISITES
  • Understanding of Halbach Array configurations
  • Knowledge of electromagnetic induction principles
  • Familiarity with toroidal solenoids and their magnetic field characteristics
  • Basic concepts of magnetic flux and its behavior in closed loops
NEXT STEPS
  • Research the principles of electromagnetic induction and Faraday's Law
  • Explore the design and applications of Halbach Arrays in magnetic field enhancement
  • Study the characteristics and limitations of toroidal solenoids in generating external magnetic fields
  • Investigate modeling software for magnetostatic simulations to analyze magnetic field interactions
USEFUL FOR

Engineers, physicists, and hobbyists interested in electromagnetic systems, magnetic field generation, and applications in non-destructive testing (NDT) or therapeutic devices.

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
