Discussion Overview

The discussion revolves around the creation of a symmetrical electromagnetic field using two cylindrical poles. Participants explore the design and control of electromagnets, specifically focusing on polarity, circuit configuration, and the type of power supply to use.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in creating an electromagnet with two vertical cylindrical poles to achieve a symmetrical magnetic field.
  • Another participant questions the broadness of the initial inquiry, indicating a need for more specific information.
  • A participant with prior experience in making electromagnets asks how to control the polarity while keeping both poles on the same circuit.
  • It is suggested that polarity can be controlled by reversing the direction of current, with a caution against using AC power for this application.
  • A participant proposes that the two electromagnets could be wound in opposite directions to achieve the desired effect.
  • Concerns are raised about the safety and knowledge of the original poster, with a recommendation to seek guidance from a teacher or join a physics club.
  • The original poster asserts their familiarity with electromagnets and clarifies that their main question pertains to circuit configuration.

Areas of Agreement / Disagreement

Participants express differing levels of confidence regarding the original poster's understanding of electromagnetism. There is no consensus on the best approach to achieve the desired electromagnetic setup, and multiple viewpoints on safety and knowledge levels are present.

Contextual Notes

Participants have not fully explored the implications of using AC versus DC power in this context, and there are unresolved questions about the specific circuit configuration needed to achieve the desired polarity.

Greetings. I need help making an electromagnet. I would make it out of copper coil and a rare Earth metal, undecided on that point yet. I know how to make a basic one but this one has to have two (2) cylindrical poles, that would remain vertical above each other. It cannot be a horseshoe magnet, because I want an even and symmetrical magnetic field. Even two separate magnets of different polarities would work fine for me
 
Physics news on Phys.org
Do you know anything about electromagnets? I don't know how to help you, as this is a pretty broad question.
 
I have made electromagnets before this. I just need help making this exact setup. How would i control the polarity of an electromagnet is a better way to ask that. I need them also to be on the same circut if possible. And shouldi use AC or DC power.
 
Polarity is controlled by the direction of current. Switch the direction and the polarity switches. I don't know why you would use AC power, as that would be more for making a transformer, not an electromagnet. If you want them on the same circuit...just put them on the same circuit?
 
Thanks. I guess my question about the same circuit thing was how do I have the DC current going in two separate directions while still being on the same circuit.
 
Just wind the magnets in opposite directions.
 
Just be very careful beatlemaniac, clearly, you know very little about electromagnetism or electricity to be given advise over a forum like this one. Nobody around here is going to want to be liable for anything you do based on their advise. Go to a teacher, join a physics club or something, do not go at it alone at this time.

Be safe.
 
Thanks for the concern Gsal. I do know a lot about electromagnets and electromagnetism. I have made them before and I have made ones of different polarity. I just needed help putting them on the same circut.
