-==== Project 12B: TBD ====
+==== Project 12B: Marty McFly and Magnetite Hill ====
+You and your team were just minding your own business and trying to finish up your semester, when out of the blue, you were contacted by the famous time travelers Doc Brown and Marty McFly! Apparently they’ve been stranded in 2021 and need your help to get back to 1985!
+The power source in their time machine (which is modeled after a DeLorean sports car) seems to be on the fritz. Doc Brown seems to think that they only need 2 V to get their time machine working again. Marty has suggested wrapping some 12-gauge copper wire 500 times around the DeLorean and then driving it down Magnetite Hill, which has a constant B-field of 10 mT that points straight up out of the ground. Marty has already done some research on Magnetite Hill and provided the graph below, which outlines how the angle of the hill changes with time when he’s driving at a constant 35 mph. However, Doc Brown is very concerned about Marty’s plan - he’s worried that there will be magnetic force on the wire that will crush the DeLorean leaving them stranded in time forever!

+Thus, Doc and Marty have come to you for help. They need to know if Marty’s plan will create the 2 V they need for their time machine without crushing the DeLorean in the process. Remember, a good solution is not just equations and numeric calculations, but will include commentary and discussion of those equations, reflections on what those predictions mean, and the limitations of your solution.

+=== Learning Goals ===
+  * Use a graph to determine when/where the largest $V_{ind}$ would occur
+  * Calculate the $V_{ind}$ using the change in magnetic flux
+  * Use the right hand rule to determine the direction of the induced current
+  * Use the right hand rule to determine the direction of the magnetic force from the induced current
