Magnetic Moment Of Steel and Iron Wire

AI Thread Summary
The magnetic moment of steel and iron wire depends on whether the wire is magnetized and the specific magnetization level. To calculate the magnetic moment (M) for a wire of length L, the formula M = m*L is used, where m represents the magnetic pole strength. Users are seeking methods to determine the value of m for iron or steel wires, particularly when using a magnetize/demagnetize device. Understanding the magnetization process is crucial for accurate calculations. The discussion emphasizes the need for clarity on the magnetization properties of the materials involved.

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?
 

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
