2nd PUC Electromagnetic Induction – Most Repeated 2-Mark Questions

Electromagnetic Induction is one of the most important chapters in 2nd PUC Physics and carries a high weightage in board exams. This chapter explains how electric current is generated using magnetic fields, and it forms the foundation for generators, transformers, induction motors, and almost all power-generation systems used in daily life. In this video, we clearly explain all important questions, derivations, concepts, and repeated board exam topics from Electromagnetic Induction. Students preparing for Karnataka 2nd PUC Science (Physics) can use this explanation as a complete revision guide.

The lesson covers Faraday’s laws of electromagnetic induction, Lenz’s law, eddy currents, motional emf, flux, flux change, and calculation-based problems that frequently appear in board exams. We also discuss real-life applications such as electric generators, AC dynamo, transformers, magnetic braking, induction heating, and energy conversion. All these topics are simplified to help even average students understand easily and score full marks.

This video includes step-by-step explanations of derivations such as emf induced in a rotating coil, emf induced in a straight conductor moving in a magnetic field, expression for AC generator, and reasoning questions like the direction of induced current and role of Lenz’s law in energy conservation. The important 1-mark, 2-mark, 3-mark, and 5-mark questions are highlighted with easy memory techniques, expected question patterns, and Karnataka PUC model paper questions.

Whether you are revising for mid-term, preparatory exams, or board exams, this content ensures a complete understanding of Electromagnetic Induction. The explanation follows the official NCERT + Karnataka PUC syllabus and helps students confidently answer theory and numerical problems. Make sure to watch till the end for exam tips, short notes, and frequently repeated questions.
