1. When a wire loop surrounds a stationary magnet, no current flows in the loop. What Faraday and henry discovered was that moving the magnet causes a current to flow in the loop. It does not matter whether the magnet or the loop is actually being moved; the origin of the current lies in the relative motion between a conductor and a magnetic field

2. A lever is a rigid rod pivoted at a certain point called the fulcrum. Fig. 12-1 shows the most familiar type of lever, with a load at one end being balanced by an applied force at the other. The condition for equilibrium is that the torques produced by Fin and Fout be the same in magnitude

3.兴兴兴: male and born in december1941.He graduated from the Xi'an Military Telecommunications Engineering Institute (the predecessor of Xidian University) and remained at the institute as a faculty member. From 1981 to 1983 he stayed at the University of Pennsylvania, U.S.A. for further studies, engaged in the research on image analysis &processing and radar imaging. From 1989 to 1990 he went to the united states and britain successively as a visiting scholar. Currently he serves as president of shenzhen University, being an advisor for doctoral students of Xidian University in the academic area of signal and information processing, he gas been in charge of and undertaken quite a few projects, all with high-level achievements
