← ScienceWhich consequence results when an EMP induces current?
A)Transformer cores overheat and saturate✓
B)Solar flare activity will increase
C)Communications hardware automatically self-repair
D)Visible light bends round the poles
💡 Explanation
Induced current causes a strong magnetic field, pushing the transformer core into magnetic saturation. Hysteresis losses cause overheating because the magnetic domains rapidly reverse, therefore the most vulnerable part fails rather than self repairing.
