Its speciality is that -1.emf always increases 2.it can be increased in both directions of y axis.......first charge the cpacitor.......tap on the switch-u get huge voltage.......tap again ......the curve follow sine function.....now depending on if u tap when the curve is above or below x axis .....curve will increase in that corresponding direction...........see it yourselves...............................................................................i added a new switch for discharging the capacitor ......i'll try to modify the circuit .............expect new comments
