← ScienceWhich outcome occurs when a tokamak's magnetic coil current collapses faster?
A)Increased localized plasma disruptions arise✓
B)Uniform plasma heating becomes immediate
C)Neutron flux decreases almost linearly
D)Confinement time instantaneously plateaus
💡 Explanation
Rapid current collapse induces a quickly-changing magnetic field, causing Electromagnetic Induction resulting in large, opposing electromotive forces internally. This results in highly localized plasma instabilities rather than uniform heating, because the collapse concentrates field energy unevenly; therefore, plasma confinement fails catastrophically.
