| Several properties of magnets: 1. The energized conductor is placed in the magnetic cymbal and will be subjected to the magnetic effect, and the direction of motion is determined by the left hand rule. 2. A part of the conductor in the closed loop generates an induced current in the magnet bore, called electromagnetic induction. 3. Electricity and magnetism can change from each other in different ways. 4. The permanent magnet has a strip shape, a hoof shape and a needle shape. 5, the permanent magnet has directivity: indicating the north-south direction, such as the compass. 6. There are north and south poles (N and S poles). The cut is still in the north and south poles and cannot exist as a single magnetic pole. 7. Depicting the magnetic induction line of the magnetic yoke. (Or the magnetic field line is a man-made curve of the magnetic steel. It goes out from the N pole of the magnet and enters the S pole. The magnetic line is represented by a more magnet image. Put a piece of paper on the magnet, evenly spread the iron filings, tap it, you can Seeing a few artificial curves, the magnets are the most dense at both ends, clarifying that the magnetism is the strongest, called the magnetic pole.) 8. The mutual effect between the magnetic poles: the same name magnetic pole repels, the different name magnetic pole attracts. 9, permanent magnets can attract magnetic substances: iron, cobalt, nickel. |
