Five study segments of the Self-Paced Physics Course materials are presented in this seventh problems and solutions book used as a part of student course work. The content is related to magnetic fields, magnetic moments, forces on charged particles in magnetic fields, electron volts, cyclotron, electronic charge to mass ratio, current-carrying loops, torques, electric motors, magnetic flux, earth's magnetic fields, Ampere's law, solenoids, toroids, and Biot-Savart law. Contained in each segment are an information panel, core problems enclosed in a box, core-primed questions, scrambled problem solutions, and true-false questions. Study guides are provided and used to answer the true-false questions and to reveal directions for reaching solutions. When the core problem is answered incorrectly, the study guide requires students to follow the remedial or enabling loop, leading to the solutions of core-primed questions. Also included is a sheet of problem numbers with corresponding page numbers which locate correct answers. (Related documents are SE 016 065 - SE 016 088 and ED 062 123 - ED 062 125.) (CC)
