Can Magnets Be Reoriented to Confine Their Field?

Click For Summary
SUMMARY

This discussion centers on the challenge of reorienting magnets to confine their magnetic field for a device intended to lift small iron (Fe) particles. The user is exploring the use of rare Earth magnets and has attempted to create a switchable, lightweight electromagnet powered by D-Cell batteries but has not achieved sufficient strength. They discovered MagSwitch devices, which operate without power, and are seeking clarification on the orientation of coils in magnetic stacking diagrams from Thyssenkrupp Magnettechnik.

PREREQUISITES
  • Understanding of magnetic field principles
  • Familiarity with rare Earth magnets
  • Basic knowledge of electromagnet design
  • Experience with magnetic stacking techniques
NEXT STEPS
  • Research the design and operation of MagSwitch devices
  • Study the principles of magnetic field confinement
  • Learn about the construction and orientation of electromagnets
  • Examine the Thyssenkrupp Magnettechnik stacking diagrams in detail
USEFUL FOR

Engineers, hobbyists, and researchers interested in magnet technology, electromagnet design, and applications for lifting small ferromagnetic particles.

Hey everyone,

I am wondering if there is a way to orient magnets so that the field is contained.

Little background, i am trying to develop a device that can lift small Fe particles. I determined that a rare Earth magnet will do the trick but i need it to be switchable and small/lightweight. So i tried to build an electromagnet powered by 1 or 2 D-Cell batteries but can't seem to come up with anything strong enough.

I found these MagSwitch devices that are small, lightweight and are easy to operate (turn of a switch) and use NO POWER. This is interesting but i can't figure out how they do it. To use a few magnets and arrange them so that there is no field doesn't make sense to me...

Also found this link: http://www.thyssenkrupp-magnettechnik.com/pdf/stacking.pdf

But am having a hard time working out the orientation of the "coil" in each diagram. Is the coil just one large coil wrapped around the center lug in types 1, 2 and 2b? Or is it two small coils oriented with poles vertically or horizontally?

ANY help is much appreciated!

Thank you
Chris

Interesting, I'll have to look into this some more.
