7. An innite solenoid with radius R501 and 11 turns per meter has its symmetry axis along the z axis, and carries a timedependent current [(1') = Iocos(a)t) where 10 and a) are constants. Outside the solenoid is a circular loop of wire with radius R10013 0036 > R501. The loop's center lies on the z axis, and the loop's symmetry axis makes an angle (9 with respect to the z axis (see the gure). Find the (time-dependent) EMF around the loop. a" A ' 2Rloop sol
