Magnetic Moment Of Steel and Iron Wire

Click For Summary

Discussion Overview

The discussion revolves around the magnetic moment of steel and iron wires of varying lengths (10, 20, or 30 cm). Participants explore the factors influencing magnetic moment, including magnetization and pole strength, and inquire about relevant equations for calculation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the magnetic moment of steel and iron wires and seeks an equation for its derivation.
  • Another participant notes that the magnetic moment depends on whether the wire is magnetized and the extent of its magnetization.
  • A participant with a magnetize/demagnetize device asks how to determine the magnetization of the wire, questioning if it corresponds to the device's magnetization.
  • Another participant claims that the magnetic moment of a wire can be expressed as M = m*L, where m is the magnetic pole strength, and seeks to calculate the value of m for iron or steel wires.

Areas of Agreement / Disagreement

Participants express differing views on the factors affecting magnetic moment, particularly regarding the role of magnetization. The discussion remains unresolved with no consensus on the calculation methods or values for magnetic pole strength.

Contextual Notes

Participants have not established specific assumptions regarding the definitions of magnetization or magnetic pole strength, and the discussion lacks clarity on the conditions under which the magnetic moment is calculated.

Hello all,

i would like to ask which is the magnetic moment of a steel and a iron wire with a length of 10,20 or 30cm!
Is there any equation from which the magnetic moment can be derived?


Thanks in advance :)!

No, since it depends on whether the wire is magnetized or not (and if it is, what the magnetization is).
 
Hello!

Thanx for your reply! I have a magnitize/demagnitize device and i want to magnetize a wire! How do i find the magnetization?

Is it the magnetization of the device?
 
actually i found out that the magnetic moment of a wire with length L is M , where M = m*L. m is the magnetic pole strength.

how can i calculate the value m for a iron or steel wire?
