**课程名称：** 电流的磁效应 (包含印地语和英语) **课程概述：** 本课程深入探讨了电流与磁场之间的密切联系，其起源可追溯至2000多年前。课程从1820年奥斯特发现载流直导线能使磁针偏转的实验讲起，阐述了载流导线周围存在磁场这一关键概念。通过观察导线周围的磁针定向以及铁屑的圆周排列，揭示了运动电荷（即电流）产生磁场的规律。 **课程将重点讲解以下内容：** 1. **电流的磁效应：** 详细解析电流如何产生磁场。 2. **磁场对运动电荷和载流导线的作用力：** 学习磁场如何对电子、质子等运动电荷以及载流导线施加 lực。 3. **回旋加速器：** 了解其工作原理，以及如何利用磁场将带电粒子加速到极高能量。 4. **检流计：** 学习电流和电压的检测与测量方法。 5. **毕奥-萨伐尔定律：** 掌握计算不同电流分布产生的磁场的方法. 6. **右手定则：** 学习判断磁场方向的有力工具。 7. **载流直导线周围的磁场：** 探讨一类基础的磁场分布. 8. **载流圆形线圈中心点的磁场：** 分析圆形电流的磁场特性. 9. **载流圆形线圈轴线上某点的磁场：** 进一步研究圆形线圈轴向的磁场分布. 10. **各种载流构型的磁场：** 拓展到更复杂的电流分布产生的磁场。 11. **安培环路定理：** 学习利用安培环路定理简化磁场计算. 12. **安培环路定理的应用：** 探索该定理在解决磁场问题中的实际应用. 13. **无限长载流直导线的磁场：** 分析理想化情况下的磁场分布. 14. **载流长圆柱体的磁场：** 研究圆柱形导体内的磁场. 15. **螺线管：** 探讨螺线管的磁场特性及其应用.
Both electricity and magnetism have been known for more than 2000 years. However thier intimate relationship was discovered only 200 years ago. oersted discovered in the year 1820 that a straight wire carrying current caused a noticeabledeflection in a nearby magnetic compass needle. The wire carrying current must be associated with the magnetic field causing deflection in the compass needle.When a wire carrying current is held perpendicular to the plane of paper and a ring of compass needle surrounds the wire the orientation of needle is tangential on magnetic field lines.If we sprinkle iron fillings around the wire carrying current they arrange themselves i concentric circleswith the wire as the centre. Oersted thus concluded that moving charges or currents produce magnetic field in the surrounding space. In this course we will study1. How current produce magnetic field 2. How magnetic field exert forces on moving charged particles like electrons , protons and current carrying wires.3. How charged particles can be accelerated to very high energies in a cyclotron4. How current and voltages are detected and measured by a galvanometer.5. Biot savart law6. Flemings left hand rule7. Magnetic field due to straight wire carrying current 8. Magnetic field at the centre of the circular wire carrying current9. Magnetic field at a point on the axis of a circular coil carrying current.10.Magnetic field due to various current carrying configurations11. Amperes circuital law.12. Applications of Amperes circuital law.13. Magnetic field due to infinite long straight wire carrying current.14. Magnetic field due to current through a very long circular cylnider.15.The solenoid.
