Magnetic Moment Of Steel and Iron Wire

Click For 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 'What determines if wave components are independent vs coherent?'

I'm working through something and want to make sure I understand the physics. In a system with three wave components at 120° phase separation, the total energy calculation depends on how we treat them: If coherent (add amplitudes first, then square): E = (A₁ + A₂ + A₃)² = 0 If independent (square each, then add): E = A₁² + A₂² + A₃² = 3/2 = constant In three-phase electrical systems, we treat the phases as independent — total power is sum of individual powers. In light interference...
