Click For Summary

Discussion Overview

The discussion revolves around understanding magnetic flux density in coils, specifically seeking a general equation that relates flux density to electric current, coil dimensions, and the number of turns. The scope includes theoretical aspects and relationships between magnetic field and flux density.

Discussion Character

  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant inquires about a general equation connecting magnetic flux density to electric current, coil dimensions, and number of turns.
  • Another participant suggests that the relationship should be found in the inquirer's notes and questions their knowledge of the magnetic field in a coil and the relationship between flux density and magnetic field.
  • A later reply indicates that a website provides a good explanation of the relationship between magnetic field and solenoids, implying that understanding this relationship is crucial.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants provide different levels of guidance and resources without settling on a specific equation or relationship.

Contextual Notes

Participants reference external resources for further clarification, indicating that the discussion may depend on the definitions and contexts provided by those sources.

Hello,

I am looking into magnetic flux density in coils can anyone tell me if there is a general equation that equates flux density to the electric current, the coil's dimensions and number of turns?

Any help would be appreciated.

Thanks.

Welcome to PF;
You should have that relationship in your notes already ...
Do you know how to find the magnetic field in a coil?
Do you now the relationship between flux density and magnetic field?

Well done - that site tells you about the magnetic field in a solenoid - if you know the relationship between magnetic field and magnetic flux density, you are set :)
