Where is magnetic field strongest in a solenoid?

Click For Summary

Discussion Overview

The discussion revolves around the characteristics of the magnetic field in a solenoid, particularly where it is strongest, and the relationship between electric and magnetic fields in this context. Participants explore experimental data, theoretical principles, and connections between electric fields and changing magnetic fields.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that the magnetic field is strongest at the center of the solenoid, but notes that the difference is not significant.
  • Another participant states that the magnetic field inside the solenoid is generally constant and references Ampere's law as a method to find it.
  • There is a question about how to connect the electric field with the solenoid experiment, with one participant indicating that an electric field exists only when the magnetic field is changing.
  • A participant expresses confusion about the nature of electric fields, questioning how they can exist in a solenoid if they are typically associated with charge.
  • One participant cites Maxwell's equations, indicating that electric fields can arise from either charges or changing magnetic fields.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specifics of the electric field within the solenoid or the implications of changing magnetic fields. Multiple viewpoints on the relationship between electric and magnetic fields are presented, indicating ongoing debate.

Contextual Notes

The discussion includes assumptions about the behavior of electric fields in relation to magnetic fields, and the application of theoretical laws such as Ampere's law and Maxwell's equations. Some participants express uncertainty about the definitions and conditions under which these fields operate.

Who May Find This Useful

This discussion may be of interest to those studying electromagnetism, particularly in relation to solenoids, as well as individuals conducting experiments involving magnetic and electric fields.

Where is magnetic field strongest in a solenoid?
 
Physics news on Phys.org
What do you know about solenoids and what have you done so far?
 
I have been an experiment of my own and have collected some data.

When a current is produced in a coil it produces an electromagnetic field at the center of the coil parallel to it's length.

The data I corrected shows that the magnetic field is strongest at the center of the solenoid is that right? but the difference is really not great.

Suppose I was supposed to identify the electric field and the electric potential where would I assume that?
 
The magnetic field inside the solenoid is pretty much constant on the inside. You could use amperes law to find it.
 
How would you connect electric field with a solenoid experiment?

I am not sure what you're asking for but you would have an electric field inside the solenoid only while the magnetic field is changing.

But how is that possible, I thoughtn electric field is by per charge? Where exactly will the electric field be inside a solenoid?
 
atleast maxwell's equation tells that a cause for an electric field is either a charge or a changing magnetic field.
curl E=-(dB)/(dt);
