A horizontal solenoid is connected to a cell and a switch, Fig. A Copper ring with its axis along the axis of the solenoid is placed on a frictionless track. What happen to the ring, as the switch is closed ?

move towards the solenoid

remain stationary

move away from the solenoid

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

A solenoid 60 cm long and of radius 4 cm has 3 layer of windings 300 turns each. A 2.3 cm long wire of mass 2.5g lies inside the solenoide near its center normal to its axis, both the wire and the axis of the solenoid are in the horizontal plane. The wire is connected through two leads parallel to the axis of the solenoid to an external battery which supplies a current of 6A in the wire. What value of current (with appropriate sense of circulation) in the windings of the solenoid can support the weight of the wire?
