← ScienceWhich mechanism undermines magnetic confinement in fusion reactors?
A)Curvature gradient drift instability
B)Bootstrap current disruption mode
C)Resistive tearing mode formation✓
D)Alfvén wave heating resonance
💡 Explanation
Resistive tearing mode causes magnetic island formation leading to field line reconnection and plasma escape from the reactor, because it undermines containment by disrupting field topology; therefore leading to confinement loss, rather than instabilities from particle drift causing minor losses.
