Electromagnetic induction question

Click For Summary

Discussion Overview

The discussion revolves around electromagnetic induction, specifically the relationship between induced current in a coil and the magnetic field produced by that current. Participants explore the conditions under which a magnetic field is generated when a coil is moved within a magnetic field and whether this induced current also creates a magnetic field around the coil.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant states that when a current passes through a wire, a magnetic field is produced, and this can be amplified with a coil.
  • Another participant confirms that if a current flows through a coil, it produces a magnetic field, regardless of external magnetic fields.
  • A participant seeks clarification on whether moving a coil in a magnetic field to create current flow will also result in the coil producing a magnetic field.
  • One participant asserts that the induced current will indeed produce a magnetic field.

Areas of Agreement / Disagreement

There appears to be some agreement that an induced current will produce a magnetic field, but the discussion includes varying levels of clarity and understanding regarding the conditions and implications of this phenomenon.

Contextual Notes

Some participants express confusion regarding the phrasing of questions and the specifics of electromagnetic induction, indicating potential gaps in understanding or assumptions about the topic.

Hello

I am new to this forum and wanted to ask a question on em induction.

I know if a current passes through a wire a magnetic field around the wire is produced and can be amplified by having a coil of wire. If that is then placed in a magnetic field (like between a north and south pole magnetic) motion will be produced.

With induction if a wire/coil experiences a change in magnetic field by movement of either magnet or wire, then a voltage/P.D will be produced and maybe current if it is connected to a load.

What I want to know is if current does flow through the coil during em induction when a voltage is being produced by the coil/wire will there be a magnetic field produced around the coil/wire itself as current is flowing through it?

Thank you for reading and any replies.

Can you add some punctuation marks? It is hard to read your post.

If a current flows through a coil, it produces a magnetic field, even if there are other external magnetic fields or anything else.
 
Sorry my question is confusing.

If current flows through a coil, (like from a battery) then is produces a magnetic field.
So if I move a coil in a magnetic field, to create a current flow through the coil will it also turn into a magnetic?
 
The induced current will produce a magnetic field, right.
 
Thank you for the answer mfb.
