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...
3 - Phase Induction Motor 3 Phase Induction Motor: Construction and Working Principle A three-phase induction motor is a common type of electric motor used in various industrial and commercial applications. It operates on the principles of electromagnetic induction and consists of two main parts: the stator and the rotor. Here's an overview of the construction and working principle of a three-phase induction motor: Construction: Stator: The stator is the stationary part of the motor and consists of laminated iron cores with slots to hold the stator windings. The stator windings are typically designed for three-phase AC power and are evenly spaced around the inner circumference of the motor. Rotor: The rotor is the rotating part of the motor. There are two main types of rotors used in three-phase induction motors: Squirrel Cage Rotor: This is the most common type of rotor. It consists of a set of laminated iron cores with aluminum or copper bars (short-circuited conductors) arranged...
