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

Click For Summary
SUMMARY

Running an electrical current through an iron magnet can lead to demagnetization due to heat generated from electrical resistance. The induced magnetic field from the current can interact with the magnet's domains, potentially causing a slight magnetizing or demagnetizing effect depending on their orientation. Overall, the primary outcome is a reduction in the magnet's magnetic properties due to thermal effects.

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.
 
Physics news on Phys.org
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.
