← ScienceWhich state arises when certain alloys exhibit Meissner effect?
A)Superconductivity induces zero electrical resistance✓
B)Ferromagnetism generates strong magnetic domains
C)Paramagnetism aligns with magnetic field
D)Diamagnetism repels magnetic fields weakly
💡 Explanation
Superconductivity occurs because complete expulsion of magnetic fields through the Meissner effect induces zero electrical resistance in certain alloys at critical transition temperatures; therefore the material becomes superconducting, rather than exhibiting simple magnetic behaviour.
