+==== Project 12B: Manny's Magnetic Brakes ====
+Having dealt with kidnapped colleagues, reunited boar-tiger cubs, and all together just survived the semester, the citizens of Lakeview have now gotten bored. They've decided they definitely need an amusement park full of thrill rides for their town. You and your team have been paired with Manny Hallabero to work on the backup brake system for the "Tower of Doom" ride. Manny has suggested that if all the normal brake systems fail, you can simply put a large magnet in the base of the tower and that will act to slow down the cart (no power source, no moving parts needed!). This seems like a wild idea, but it just might work! Manny has shared some of his initial drawings and data.

+You and your team have been asked to consult by the city of Lakeview, given your reliable expertise. They would like you to create a report that includes: updated drawings (with magnetic field, force, induced current shown), an explanation for how this system would work as a brake for the cart, and the maximum  $V_{ind}$  in the cart. Of course, they would also like to know any assumptions you make in your report, any limitations of your findings, and your honest evaluation of whether this would work as a brake system. 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 ===
+  * Draw the magnetic field from the bar magnet
+  * Use the right hand rule to determine the direction of the induced current
+  * Determine which part of the magnetic field makes the force & use the right hand rule to determine the direction of the magnetic force from the induced current
+  * Use a graph to determine when/where the largest  $V_{ind}$  would occur
+  * Calculate the  $V_{ind}$  using the change in magnetic flux

 ==== 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!
