You placed a 17.7 cm diameter conducting coil with 23 turns in a vertical position on a lab bench and you are holding it so that it will not fall sideways. That means the plane of the coil is perpendicular to the top of the bench. There is a uniform magnetic field of 0.51 T pointing upward from the bench surface. When you take your hands off of the coil, it will fall sideways on the bench in 0.19 seconds. Determine the average emf induced in the coil during this time, and identify the current direction in the coil (from your view) while it is falling.

a coil of 82 turns is 68.18x10^-3 m in radius and has its plane perpendicular to a 8 T magnetic field produced by a nearby electromagnet. Ther current in the electromagnet is turned off leading the field to disappear and causing an emf to be induced in the coil. if it takes 17 x 10^-3 seconds for the field to disappear. calculate magnitude of the emf induced in the coil in units of V.
