A) If a circular loop of wire of radius 15.4 cm is located in a region where the spatially uniform magnetic field perpendicular to the plane of the loop is changing at a rate of +1.4 ? 10?3 T/s, find the value of the induced EMF in this loop due to this changing magnetic field.
B) Suppose we are given a square coil that is 5.5 cm on a side containing 100 loops of very fine wire. The total resistance of this coil is 2.0 ? 10?3 ?. This coil is initially centered on the origin with its sides parallel to thex- and y-axes. It is being rotated about the y-axis in a uniform magnetic field of 1.4 T along the z-axis, with an angular velocity of 2.5 rad/sec. Find the magnitude of the peak value of the induced current flowing in this coil under these conditions.
