1. The main knowledge points examined include: history of electromagnetism, geomagnetism and its applications, magnetic induction lines, magnetic effects of currents (Oster test), determination of energized solenoid poles, electromagnets and their applications, electromagnetic induction, and generators Principles of motors and motors, the action of currents on magnetic fields, electromagnetic waves, etc. Among them, Oster’s experiments, energizing solenoids, electromagnets and their applications, the principles of generators and motors, and other points of knowledge are the focus of examination. The drawing questions are mainly magnetic induction lines (judgment direction and magnetic poles), energization solenoids (determination of magnetic poles, current direction, positive and negative poles of the power supply, and windings) and electromagnets (determination of magnetic poles, electrodes, current direction, positive and negative polarities of the power supply). , Windings and physical maps), etc., The experimental question is mainly for the electromagnet exploration.
