Question

(a) What is the induced emf on a wire if exposed to a uniform magnetic field pointing toward the page as shown below. (b) What is the induced emf if the magnetic field is a function of time, B(t). (c) What if instead of a wire we a have a disk spinning at a constant angular velocity ω. What is the induced magnetic field

(This is a Faraday’s Dynamo)

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
