As seen in the figure, a square loop of wire has sides of length 2.2 cm. A magnetic field is directed out of the page; its magnitude is given by B = 5.5thy, where B is in teslas, t is in seconds, and y is in meters. At t = 3.3 s, what are the (a) magnitude and (b) direction of emf induced in the loop? (a) Number 11 Units V (b) clockwiseA long solenoid has a diameter of 15.6 cm. When a current i exists in its windings, a uniform magnetic field of magnitude B = 22.5 mT is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 6.74 mT/s. Calculate the magnitude of the induced electric field (a) 4.00 cm and (b) 9.87 cm from the axis of the solenoid. (a) Number Units (b) Number i Units V
