प्रश्न
Two bar magnets are quickly moved towards a metallic loop connected across a capacitor ‘C’ as shown in the figure. Predict the polarity of the capacitor.
उत्तर
Red lines represent the magnetic lines due to the magnets. Blue line represents the magnetic line due to the current induced in the loop.
Polarity of the capacitor: lower plate is positive; upper plate is negative.
