← ScienceWhich consequence results when exceeding the Curie temperature in hard-drive read heads?
A)Demagnetization impairs accurate data retrieval✓
B)Increased magnetoresistance creates false positives
C)Reduced thermal expansion causes head crashes
D)Enhanced permeability yields signal amplification
💡 Explanation
Above the Curie temperature, ferromagnetic materials lose permanent magnetism because thermal agitation overcomes exchange interactions, therefore the alloy demagnetizes, rather than maintaining or enhancing its magnetic orientation at operating temperatures.
