NCERT Exemplar Class 10 Science Chapter 13 – Magnetic Effects of Electric Current
The NCERT Exemplar Class 10 Science Solutions for Chapter 13 – Magnetic Effects of Electric Current introduce students to one of the most exciting areas of physics—electromagnetism. This chapter explains how electricity and magnetism are interrelated and how these principles are applied in technology and daily life. With the support of NCERT Solutions for Class 10 Science, learners gain conceptual clarity along with problem-solving practice. The chapter begins with Oersted’s experiment, which demonstrated that a current-carrying conductor produces a magnetic field around it. This fundamental discovery laid the foundation for electromagnetism. Students learn to determine the direction of the magnetic field using the Right-Hand Thumb Rule, which provides a simple method for visualizing field patterns. Next, the chapter explains the magnetic field due to a current-carrying conductor, a circular loop, and a solenoid. The properties of magnetic field lines and their representation through diagrams are discussed in detail. Solenoids and electromagnets are highlighted for their wide applications in devices like electric bells, relays, and motors.
The chapter also covers force on a current-carrying conductor in a magnetic field, explained through Fleming’s Left-Hand Rule. This principle forms the basis of electric motors, which are studied in detail, including their construction, working, and uses. Students also learn about electromagnetic induction, where a change in magnetic field induces current in a conductor. This is explained using Fleming’s Right-Hand Rule, which is essential for understanding the working of electric generators. By solving NCERT Exemplar Class 10 Science questions, students practice numerical problems, reasoning-based questions, and applications of electromagnetism. The chapter also emphasizes practical devices such as electric motors and generators, which convert electrical energy to mechanical energy and vice versa. The NCERT Solutions for Class 10 Science Chapter 13 provide detailed explanations, helping learners tackle exam-based questions confidently. This ensures readiness for both board exams and competitive entrance tests. In conclusion, Chapter 13 links electricity and magnetism with real-life applications, from household devices to industrial machines. It builds a strong base for advanced physics topics, ensuring students can understand and apply the principles of electromagnetism effectively.
