Chapter 13 Magnetic effects of electric current Part three Hello students. Today we are going to continue a discussion on magnetic effect of electric current. In our previous video, we learned about the force experienced by a charge or a current carrying conductor, then placed in an external magnetic field. We also learned about the Fleming's left hand rule, which helps us in determining the directions of magnetic field, electric, current and force based on the available data. Further, we looked into the practical application of force acting on a conductor when kept in a magnetic field in the form of electric motor. We learned about the working principle of an electric motor and also looked a bit into the commercial motors. With this background and mine, let us move ahead to the next topic that is electromagnetic introduction. So we saw that a current carrying conductor experiences of force when placed in a magnetic field, and the displacement is maximum when the direction of current and the direction of magnetic field are perpendicular to each other as well as perpendicular to the direction of force. But what will happen if the conductor smoothing inside a magnetic field or magnetic field is changing around a fixed conductor. We already know that changing current and a magnetic fixed field generates motion. So will the reverse be possible?
