Concept

Problem: A solenoid is near a piece of iron, as shown in the figure. If a current is turned on in the solenoid, a magnetic field is created. This magnetic field will magnetize the iron, and there will be a net force between the solenoid and the iron. (Figure 1)Current in solenoid is clockwise as viewed from the Piece of iron is lined up with the axis of the solenoidA) Will the force on the iron be attractive or repulsive? (Choose one)B) Suppose this force moves the iron. Which way will the iron move?To the right away from the solenoidTo the left towards the solenoid(Choose one)C) As the iron moves, what will happen to the strength of the force?It will decreaseIt will increaseIt will not change(Choose one)
