Question
A horizontal solenoid is connected to a battery and a switch (figure). A conducting ring is placed on a frictionless surface, the axis of the ring being along the axis of the solenoid. As the switch is closed, the ring will
Options
A.move towards the solenoid
B.remain stationary
C.move away from the solenoid
D.move towards the solenoid or away from it depending on which terminal (positive or negative) of the battery is connected to the left end of the solenoid.
Solution
By moving away from solenoid the ring will resist the changing flux in it.
