← ScienceWhich mechanism causes zero DC resistance in Niobium-Titanium composites operating within an MRI?
A)Flux pinning prevents minor disruptions✓
B)Ohmic heating dominates dissipation profile
C)Thermionic emission depletes carrier density
D)Resonant tunneling facilitates DC conduction
💡 Explanation
Flux pinning causes zero resistance because magnetic flux is trapped within the material, therefore the lossless current continues, rather than dissipation through Ohmic effects being dominant under normal conditions.
