← ScienceWhich mechanism results in the observed Meissner effect?
A)Expulsion of magnetic flux lines✓
B)Increased domain boundary resistance
C)Enhanced conventional ohmic heating
D)Spontaneous symmetry lattice distortion
💡 Explanation
The Meissner effect, or expulsion of all magnetic fields, is due to complete diamagnetism generated by the persistent currents. These currents screen the magnetic field; therefore the magnetic field cannot penetrate fully, rather than being redistributed.
