Ph 103: Fundamentals of Physics III 1/14/2019Chapter 25 Worksheet 11. For the following scenarios, determine whether the magnetic flux changes or stays the same. If the magnetic flux changes, determine whether it is increasing or decreasing (and in which direction). Explain your answer.a. The magnet is held stationary to the solenoid.b. The magnet is moving toward the solenoid.c. The magnet is moving away from the solenoid.2. Find the direction of the induced current for the solenoid in the figure below. The magnet is _____a. stationary to the solenoid.b. moving toward the solenoid.c. moving away from the solenoid.N SAN SAN SAN SAN SAN SAPh 103: Fundamentals of Physics III 1/14/2019Chapter 25 Worksheet 23. What is magnetic flux? Explain your answer in terms of a loop of wire.4. Consider a single loop of wire (as shown below). The loop is placed in a magnetic field (pointing into the page). The magnitude of the magnetic field is 2.0 T.a. Sketch the magnetic field lines in the loop of wire (in the leftmost diagram).b. The magnetic field decreases in magnitude from 2.0 T to 1.0 T during a time interval of 2.0 seconds. Sketch the magnetic field lines in the loop of wire at the end of the 2.0 second interval (in the rightmost diagram).c. In what direction does the magnetic flux inside the loop change? Into the page or out of the page? Explain.d. According to Lenz’s Law, the induced current in the wire will resist the change in magnetic flux in the wire. Based on this information, what direction will the induced current move in the wire:i. Before the magnetic flux begins changing (t<0 sec)? Explain.ii. While the magnetic flux changes (0 sec < t <2.0 sec)? Explain.iii. After the magnetic flux changes (t > 2.0 sec)? Explain.e. Calculate the induced electromotive force (i.e. emf or voltage) while the magnetic field is changing. The area of the loop is 0.015 m2.Before change (t=0 sec) After change (t=2.0
