Induced EMF in Rotating Coil: Induced EMF in a rotating coil is the voltage generated across a coil when it rotates within a magnetic field. This phenomenon is a direct application of Faraday's Law of Electromagnetic Induction, stating that a changing magnetic flux through a coil induces an electromotive force (EMF). As the coil rotates, the angle between its area vector and the magnetic field lines continuously changes, leading to a change in magnetic flux and consequently, an induced EMF. This principle is fundamental to the operation of electrical generators and many other electrical machines.
