Learn Electromagnetic Induction in Physics
Electromagnetic Induction (EMI) is a cornerstone chapter in the CBSE Class 12 Physics syllabus that fundamentally shifts your understanding of electricity and magnetism. While previous chapters focused on how electric currents produce magnetic fields, this chapter explores the revolutionary reverse phenomenon: how changing magnetic fields can generate electric currents. Discovered by Michael Faraday and Joseph Henry, this principle is the foundational science behind how almost all the world's electrical power is generated today. From the massive turbines in hydroelectric dams to the transformers in your neighborhood and the wireless chargers for your smartphones, Electromagnetic Induction is the engine driving our modern, electricity-dependent world.
In this chapter, you will dive deep into the quantitative and qualitative rules governing induced currents. You will begin by exploring magnetic flux and Faraday’s Laws of Electromagnetic Induction, which establish the relationship between a changing magnetic environment and the induced Electromotive Force (EMF). A critical focus is Lenz’s Law, which provides the direction of the induced current and acts as a beautiful manifestation of the Principle of Conservation of Energy. You will also learn to calculate Motional EMF when a conductor moves through a magnetic field, and explore the phenomena of Self-Inductance and Mutual Inductance in coils. Finally, the chapter applies these concepts to explain the workings of the AC Generator, translating mechanical energy into alternating current.
The infographic above illustrates the core concept of EMI: as a bar magnet moves towards a solenoid, the magnetic flux passing through the coil increases. According to Faraday's Law, this changing flux induces an electromotive force, causing a current to flow (evident by the galvanometer deflection). By Lenz's Law, the induced current flows in a direction that creates its own "North" pole to repel the approaching magnet, thereby opposing the change. From an exam perspective, this chapter is heavily tested in CBSE Class 12 Boards. You can expect standard derivations (such as the expression for motional EMF or mutual inductance of two coaxial solenoids), conceptual questions asking you to predict the direction of induced current, and numericals applying the formula ε = -dΦ/dt. Exam Tip: Never forget the negative sign in Faraday’s formula during calculations, as it represents Lenz’s Law, and always use the Right-Hand Rule to confidently determine the direction of induced current in conceptual questions.
Mastering the intricacies of changing magnetic flux, vector directions, and integration-based derivations in Electromagnetic Induction can be challenging. If you are struggling to grasp Lenz's Law or need step-by-step help with complex motional EMF numericals, connecting with an expert can make all the difference.

I studied physics with Imran Sir in class 11 and 12. He explains the concepts properly with patience. He also taught a lot of tricks to solve questions faster. His classes are fun and i improved a lot over time studying with him.
I have been working as teacher for the last 20 years. I can taugt Physics from class 8 to 12 ( CBSE,ICSE,ISE ,IGSE and STATE)
Education can not be forced onto a student. Teaching, more than imparting knowledge, is inspiring a change. Learning, more than just reading or memorising facts, is gaining knowledge or acquiring skills by studying. My way of teaching is conceptual, analytical, simplified and problem solving. Having worked as HOD for engineering college, I also counsel students in the areas of career development and motivation towards achieving their goals. I mentored several students to achieve good results in academic and competitive exams. I worked as a professor of Physics for Engineering college for 30 years and now taking online classes since 2018. I can teach Physics and Chemistry for 10th, 11th, 12th, UG and physics for all. Currently taking online tuitions for US, Canada and Indian students in Physics and Organic chemistry My students from US are from Heritage High School, Frisco, Texas;University of Dallas, Texas, University of Wisconsin, and Simon Fraser University, B. C. Canada.
Dr Mamatha is an extremely patient and diligent teacher. She broke down each concept in simple terms and helped me understand it in the easiest way possible. She was always willing to teach me again in case I stumbled or faced difficulty in any concept. I really started to understand physics beyond the textbook and approach the concepts in an informed way, after taking classes with her!
I have been giving tuitions to Class 12 students since October 2015. I was then in 2nd year of BSc Physics from the renowned 200 years old university, Presidency University. In total I taught 2 Class 12 students in Kolkata and 9 Class 12 students in Delhi. Currently I am teaching a Class 11 student from JNU Quarters Maths, Physics and Chemistry via Zoom app. I have whiteboard, colourful pens and other requirements to ease the teaching in a great way.
With over 11 years of teaching experience, I have had the privilege of mentoring more than 5,000 students across various reputed coaching institutes in Bangalore. My teaching has primarily focused on preparing students for competitive exams, and I take pride in the fact that many of my students have successfully qualified for NEET, JEE and CET under my guidance. Throughout my career, I have been committed to delivering clear, concept-driven instruction while fostering a supportive and open classroom environment. I ensure that every student, regardless of their level, feels comfortable asking questions and engaging actively in the learning process. My ability to simplify complex topics and build strong student rapport continues to be the cornerstone of my teaching approach.
Sir explains the subject maths very well in detail.He explains all the concepts. Clears all the doubts.
