Question
The diagram at right shows a copper wire loop held in place near a solenoid. The switch in the circuit containing the solenoid is initially open. a. wire of the loop in each of the following cases. Explain your Use Lenz reasoning just after the switch has been closed loop Solenoid a long time after the switch has been closed . just after the switch has been reopened a long time after the switch has been reopened For each of the cases in which you predicted that there will be an induced current, draw a diagram that illustrates: b. the direction of the current through the wire of the loop, the direction of the magnetic moment of the loop, and the direction of the magnetic force exerted on the loop. Is the force on the wire loop in a direction that would tend to increase or decrease the change in net flux through the wire loop?Explanation / Answer
Just after switch is closed and reopened, current will flow through the wire. Since at that time there is change of magnetic field. After a long time, it will become constant so change is zero and no current will flow
