The SPM Physics Workbook is developed under the One-School.net Free Books Project. The content of this book is strictly follow Malaysia SPM (Sijil Pelajaran Malaysia) syllabus. The aim of this project is to provide a complete electronic supplementary network for students to develop self-learning skills by breaking the spoon-feed rituals and to encourage them to compile educational information from the Internet.
1. Which of the following procedures will not generate e.m.f.?
Choice 1 Holding a magnet stationary inside a coil.
Choice 2 Rotating a coil in a magnetic field.
Choice 3 Rotating a magnet around a stationary coil.
Choice 4 Moving a bar magnet across a flat piece of metal.
