No, the PF does not work like that. It is not for logs/blogs -- it is for answering specific questions, generally one question per thread. Please confine this thread here to your specific question about currents in wire loops and magnetizing bolts. Thank you.Summary:: Hello I was working on a project and got side tracked with EM fields. I opened this thread in hopes to add to it and keep it sort of like a running log. I want to start at ground 0 like a kid and expand on that base. With that let me just start with my first question.
No. It would take either a current in the wire as @Drakkith says, or a permanent magnet nearby. The Google search term would be Magnetic Induction.If you take copper wire and wrap it tightly around a bolt will that alone create and hold a magnetic field?
Sorry let me clarify. I did not mean like a blog. It will be a running question about this topic. I will just add future questions about the same topic to this instead of opening a bunch of threads. If that is acceptable.No, the PF does not work like that. It is not for logs/blogs -- it is for answering specific questions, generally one question per thread.

We can give it a try to see what happens. Please read through the link that I posted above and let us know if you have specific questions. Thank you.Sorry let me clarify. I did not mean like a blog.

That’s what I thought, but it seems I have an exception.As long as you have current running through the coil, yes. To get a permanent magnet the bolt would have to be made of a specific material. I'm not sure regular steel is easily magnetized permanently.
