← ScienceWhich mechanism prevents eddy currents forming within superconducting magnets?
A)Zero electrical resistance dominates✓
B)Increased hysteresis consumes energy
C)Flux pinning induces heating
D)Diamagnetism generates back-EMF
💡 Explanation
Zero electrical resistance forces the superconducting state; therefore alternating magnetic reversals induce negligible loss rather than parasitic currents forming; this is because any circulating current decays without dissipation, rather than generating significant eddy-current loss.
