The provided figure displays a horizontal solenoid connected to a battery and a switch. A copper ring is located on a frictionless track, with its axis aligned along the solenoid's axis. When the switch is closed, the ring will

Step-by-step solution

When the switch is closed, the current in the solenoid increases from zero to a steady maximum value. This increasing current produces an increasing magnetic field along the axis of the solenoid, which in turn increases the magnetic flux linked with the copper ring. According to Faraday's law of electromagnetic induction, an electromotive force (EMF) is induced in the ring. By Lenz's law, the direction of the induced current in the copper ring will be such that it opposes the change in magnetic flux that produced i
