Calculating Induced Magnetic Moment of Steel | Step-by-Step Guide

Click For Summary

Discussion Overview

The discussion revolves around calculating the induced magnetic moment of steel in response to an applied magnetic field. Participants explore the context of the question, including the level of complexity and the relevant physics principles involved, particularly in classical electrodynamics.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested, Homework-related

Main Points Raised

  • One participant requests guidance on calculating the induced magnetic moment of steel given an applied magnetic field.
  • Another participant asks for background information to better understand the context of the question, including the educational level.
  • A participant suggests that the question is likely at a university level.
  • There is a discussion about the variability of the answer depending on the approach, questioning whether the context is classical electrodynamics or condensed matter physics, and whether it is introductory or advanced.
  • A participant indicates that the question is at an introductory level and suggests keeping the explanation simple, focusing on classical electrodynamics.
  • Another participant mentions that the magnetization can typically be estimated from susceptibility, but notes that the type of steel may require consulting a magnetization curve due to potential hysteresis effects.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific approach to take for calculating the induced magnetic moment, as there are multiple considerations regarding the context and complexity of the problem.

Contextual Notes

Participants highlight the importance of the type of steel and the potential impact of hysteresis on the induced magnetization, indicating that assumptions about material properties and definitions may affect the calculations.

Excuse me, can anyone teach me how to calculate the induced magnetic moment of steel, given the applied magnetic field?
 
Physics news on Phys.org
Can you give us the background for this question ? Is it for a class - if so, what grade/level ?
 
Thx for answreing.
I think this is a University question...
 
That's not enough because the answer varies depending on what approach you take on the problem. Is this in context of classical electrodynamics or condensed matter physics? Intro or advanced(graduate level)?
 
It is only at introductory level.

Please concern it as easy as possible, classical electrodynamics I think.
 
Typically, you can estimate the magnetization from the susceptibility. But depending on the material (kind of steel) the hysteresis might ne large enough that you'd want to refer to a magnetization curve to determine the induced magnetization at a given field.
