I just need the last part h) Please show all your work. I'll rate. Thank you in advance!

Physics 1122 Quiz 4E – Exp. 7 October 22 - 24, 2019 DIRECTIONS: Work the problem. You must show all work to receive credit, and you must return this sheet. The problem is worth 20 points. If you have to construct a graph, use the graph paper provided in the laboratory. Solve the problem using only symbolic algebra and then report numerical values. You will receive half of the score for the symbolic solutions in terms of given variables, and the second half for the numerical values. Please give detailed explanations in order to receive the full credit. The figure on the left shows a 600 turn circular coil entering a region inside the dashed rectangle) where the magnetic field B is constant and equal to 1.75 Tesla. Assume B is out of the page. The 6.00 12 coil is connected to a 8.00 12 resistor. (a) For the position, shown in the coil figure, does the magnetic flux increase or decrease as the coil enters the magnetic region? (b) If the final position of the coil is completely inside of the magnetic field, calculate the change in magnetic flux if the coil started from the position represented in the figure (half of it is inside the region of the magnetic field). Travel time PAGE is 1.85 seconds. (c) If the diameter of the coil is 31.50 mm, calculate induced emf for situation represented on the figure. (d) Calculate the maximum current in the coil. (e) What is the direction of the induced current in the coil, clockwise or counter - clockwise? (f) What is the direction of the force on the coil? (g) What is the flux change while the coil is entirely inside the region of the magnetic field? (h) If the diameter of the coil is one-third the side length L of the square region where B exists, for how long, in terms of v and L, is the induced emf in the coil zero? --iout of EME

Answer 1

EMF induced is zero implies that the coil is completely inside the magnetic region for some time, such that, there is no fllux change with time.
