Students will find step-by-step solutions to textbook exercises, conceptual MCQs, short questions, and detailed long questions based on the National Book Foundation (NBF) textbook. These notes are fully aligned with the Student Learning Outcomes (SLO) framework for board exam preparation.
Chapter Overview
Chapter 8, 'Magnetism', studies the fundamental principles of magnetic force, fields, materials, and terrestrial magnetism. Students explore the Domain Theory of Magnetism, which explains magnetism at the molecular level, and calculate the force between magnetic poles. The chapter also outlines magnetic fields, detailing how to determine the direction and relative strength of fields, as well as the concept of magnetic shielding.
A major emphasis is placed on induced magnetism and the creation of temporary and permanent magnets. Students examine methods of magnetisation and demagnetisation—including stroking, hammering, heating, and using solenoids—alongside the differences between electromagnets and permanent magnets. Key applications such as magnetic recording, speakers, and door locks are also analyzed.
Finally, the chapter classifies magnetic materials into diamagnetic, paramagnetic, and ferromagnetic groups, highlighting the difference between magnetic and non-magnetic materials. It also investigates Earth's Magnetic Field, explaining geographical and magnetic poles and the concept of bio-magnetism.
