Would running an electrical current through a magnet destroy the magnet?

AI Thread Summary
Running an electrical current through a magnet can lead to demagnetization due to heat generated from resistance in the iron. The current also creates an induced magnetic field that can interact with the magnet's existing domains. This interaction may result in either a slight magnetizing or demagnetizing effect, depending on the orientation of the fields. Overall, the magnet's properties may be altered, primarily through heat-induced demagnetization. Understanding these effects is crucial for applications involving magnets and electrical currents.

Hello,

Suppose you had an iron magnet. What effect would an electrical current have on this magnet? Would it still retain its magnetic properties?

Thanks in advance for the help.

Any heat generated by the electricity through resistance of the iron would cause demagnetization. The current would also induce a magnetic field concentric to itself. Depending on the orientation of this induced magnetic field to the domains in the magnet (with respective components parallel or antiparallel), the current would conventionally have a slight magnetizing or demagnetizing effect.
 
What a great succint reply Loren...
 
Thanks for the pleasant aire.
 
Thank you, that was a very clear answer indeed.
 

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
