← ScienceWhich outcome impairs eddy current braking in locomotives crossing rail gaps?
A)Decreased magnetic field flux✓
B)Increased armature winding resistance
C)Enhanced rail track conductivity
D)Elevated wheel slip angle
💡 Explanation
Reduced rail overlap causes a drop in the induced current because the electromagnetic induction weakens. The shorter duration limits eddy current generation, therefore braking force diminishes significantly rather than exhibiting increased armature resistance effects or wheel slippage changes.
