Electromagnetic Induction I can provide you with a brief overview of the topic and some key points that are typically covered in class 12 physics notes on electromagnetic induction: Electromagnetic Induction is a fundamental concept in physics, discovered by Michael Faraday in the 19th century. It deals with the generation of an electromotive force (EMF) or voltage in a closed circuit due to a change in magnetic flux through the circuit. Key points often covered in class 12 notes on electromagnetic induction may include: 1. Faraday's Law: It states that the induced electromotive force (EMF) in a closed circuit is directly proportional to the rate of change of magnetic flux through the circuit. Mathematically, this is expressed as EMF = -d(Φ)/dt, where EMF is the induced voltage, Φ is the magnetic flux, and dt is the change in time. 2. Lenz's Law: Lenz's law is a consequence of Faraday's law and states that the direction of the induced current will be such that it oppos...
