Electricity: Magnetic and Heating Effects
This chapter of the Class 8 NCERT Curiosity textbook explores what an electric current can do besides simply flowing through a wire. Learners see how current heats thin filaments until they glow in bulbs and heaters, and why a fuse melts to protect a circuit from overload. A compass needle placed near a wire reveals the magnetic effect, leading to electromagnets, bells and motors. Simple circuits, careful testing and attention to safety show how these two effects quietly power comforts and machines in daily life.
