alleryCutting slots in the swinging copper plate makes it:
AStop even faster
BHeat up more
CStick to the poles
DSwing more freely
Answer & Solution
Correct answer: D. Swing more freely
1. Slots leave less area for eddy currents to flow.
2. Weaker eddy currents mean less damping.
3. The plate swings more freely.
