Electrifying a permanent magnet

AI Thread Summary
Passing a current through a conductive permanent magnet can alter its magnetic field. The flow of current can disrupt the alignment of magnetic domains, potentially leading to a decrease in magnetization. The direction of the current influences the orientation of the resulting magnetic field. In some cases, high current can even demagnetize the material. Understanding these effects is crucial for applications involving electromagnetism and magnetic materials.

What happens, and why? (This isn't homework, just curiosity.)

To be more precise, what would happen to the magnetic field of the magnet if we passed a current through it (assuming it is conductive). Will the current disrupt the magnetic domains? Will the magnetization disappear?

It may surprise you to know that one way to produce a permenant magnet is to pass high current through a conductive metal. The direction of the current will determine the direction of the field.

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...
