Understanding Magnetic Effects of Electric Current
A major portion of Chapter-10 Electro-magnetism focuses on the magnetic effect of electric current. Students learn that whenever an electric current flows through a conductor, a magnetic field is produced around it. The chapter explains magnetic field lines and the factors affecting the strength of the magnetic field generated by a current-carrying conductor.
The Selina solutions help students understand how current direction influences magnetic field direction and how simple experiments demonstrate this phenomenon. Important concepts such as straight conductors, circular coils, and solenoids are discussed in detail. Numerical and theory-based questions from these topics frequently appear in examinations, making them essential for scoring high marks.
Electromagnets and Their Applications
Electromagnets are one of the most important topics covered in this chapter. Students learn how a soft iron core placed inside a current-carrying coil becomes magnetized and behaves as a magnet. Unlike permanent magnets, electromagnets can be switched on and off by controlling the electric current.
The chapter explains the factors affecting the strength of an electromagnet, including the number of turns in the coil and the magnitude of current. Through Selina solutions, students gain a clear understanding of practical applications such as electric bells, cranes used for lifting scrap iron, and various industrial devices. Questions related to electromagnets are commonly included in ICSE examinations due to their practical significance.
Electromagnetic Induction, Motors and Generators
The final section of Chapter-10 Electro-magnetism introduces electromagnetic induction, a phenomenon discovered through experiments involving magnets and coils. Students learn that electricity can be generated when there is relative motion between a magnet and a conductor. This principle forms the basis of electric generators.
The chapter also explains the working principles of electric motors, which convert electrical energy into mechanical energy. Students learn the functions of important components such as armatures, brushes, and split-ring commutators. The Selina solutions simplify these concepts with clear explanations and diagrams. Since motors and generators are frequently asked in theory and diagram-based questions, mastering these topics is crucial for examination success.
