 Quizbank now resides on MyOpenMath at https://www.myopenmath.com (although I hope Wikiversity can play an important role in helping students and teachers use these questions!)
 At the moment, most of the physics questions have already been transferred. To see them, join myopenmath.com as a student, and "enroll" in one or both of the following courses:
 Quizbank physics 1 (id 60675)
 Quizbank physics 2 (id 61712)
 Quizbank astronomy (id 63705)
The enrollment key for each course is 123. They are all is set to practice mode, giving students unlimited attempts at each question. Instructors can also print out copies of the quiz for classroom use. If you have any problems leave a message at user talk:Guy vandegrift.

\question The current through the windings of a solenoid with n= 2.980E+03 turns per meter is changing at a rate dI/dt=9\,A/s. The solenoid is 88\,cm long and has a crosssectional diameter of 2.69\,cm. A small coil consisting of N=28turns wraped in a circle of diameter 1.64\,cm is placed in the middle of the solenoid such that the plane of the coil is perpendicular to the central axis of the solenoid. Assume that the infinitesolenoid approximation is valid inside the small coil. What is the emf induced in the coil?
