Answer the following question

Part II: Complete each question in the space provided. [23 Marks] 1. The diagram shows a magnet suspended near a solenoid. After the solenoid has been connected to the power supply, the magnet rotates to a new position with its south pole pointing towards the solenoid. Using the arrows in the diagram as a reference, what are the directions of both the current in the solenoid and the magnetic field caused by the current? Explain your answer.
