Question

polaned by a magnetic field. The picture to the gh shows a refrigerator magnet with the N and S poles of its dipole shown and a piece of steel. Draw the magnetic field on the steel produced by the refrigerator magnet. Think about the electrical attraction between a polar molecule and a non- Use the electrical magnet and why it then attracts the refrigerator magnet. polar molecule. analogy to explain how the steel is magnetically polarized by the refnigerato 49 Explain why motors are typically made with coils of wire wound on soft pieces of iron Almost all moto some of the rs are made by winding many turns of wire around pieces of soft iron, arranged so that c dipoles attracting and repelling each other, depending on their relative positions. Why aren't pieces of iron can turn inside the other pieces. All motors work on the principle of motors made of simple coils of wire? n each picture below electrons flow inside a tube that is evacuated (no air inside). There is an electric field in the tube that is created by electric charges placed at each end of the tube. A uniform magnetic field B is also present inside the tube, created by some external source. The magnetic field points either directly into the page or directly out of the page. For each diagram, decide if the electrons are slowing down or speeding up and decide if the magnetic field points into the page or out of the page. You may neglect gravity in this problem. Clearly explain your reasoning. Iv path path path
