← ScienceWhich risk increases when strong external magnetic fields interfere with a spacecraft's hall-effect thruster?
A)Plasma detachment from the anode✓
B)Microwave emission bandwidth reduction
C)Increased propellant ionization efficiency
D)Thruster overheating due to reduced ion focusing
💡 Explanation
When external magnetic fields interfere, they disrupt the designed magnetic confinement of plasma within the Hall-effect thruster because magnetic field lines are distorted leading to plasma detachment. Therefore, plasma detachment occurs, rather than the other effects which require optimized field alignment and confinement.
