_______ is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.

بالکل صفر برقی مزاحمت کا ایک رجحان ہے اور مخصوص مواد میں موجود مقناطیسی میدانوں کے اخراج کا واقعہ ہے جب ایک خصوصیت کے اہم درجہ حرارت سے نیچے ٹھنڈا کیا جاتا ہے۔ ______
Answer: Superconductivity
Explanation

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.

This allows for highly efficient electrical conduction and magnetic field exclusion.
