1) A uniform magnetic field B points in the direction. A circular loop of wire has radius a and resistance R. At t = 0, the loop lies in the x-y plane, with the center of the loop at the origin of coordinates. The loop rotates about the y-axis with angular velocity w. Find the current, I(t), flowing through the loop at an arbitrary time t. (Ignore/neglect any "self-induction" effects, i.e., neglect any effects of the magnetic field produced by the current in the loop.)
A flat circular coil with 153 turns, a radius of 2.46 x 10-² m, and a resistance of 0.597 £ is exposed to an external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field is changing at a rate of AB/At = 0.743 T/s, thereby inducing a current in the coil. Find the magnitude of the magnetic field at the center of the coil that is produced by the induced current. Number i Units
