प्रश्न
Predict the polarity of the capacitor in a closed circular loop when two bar magnets are moved as shown in the figure.
उत्तर
- From Lenz’s law, the direction of the induced current is in a clockwise sense.
- This implies that plate A of the capacitor is at a higher potential than plate B
- B will be a negative plate while A will be a positive plate.
