30. Induction and Inductance
Faraday's Law
28PRACTICE PROBLEM
A wire of resistance R is bent in the shape of a square with side a. This wire rotates at a frequency of f in a constant magnetic field B. Determine the expression for the induced current in the loop. Assume that at t=0 s the angle between the area vector and the magnetic field is zero.
