If a South pole moves toward the loop in the plane of the page, in what direction is the induced current? (5 points) c. A wire loop is being pulled to the left through a uniform outward magnetic field. What is the direction of the induced current? (5 points) d. A wire loop is being pulled to the right through a uniform outward magnetic field that suddenly ends. What is the direction of the induced current? (5 points) e. If a coil is expanding in a magnetic field pointing out from the page, in what direction is the induced current? (5 points) f. A wire loop is being pulled towards a current-carrying wire. What is the direction of the induced current in the loop? (5 points) 4.To make the rod move to the right at speed v, you need to apply an external force on the rod to the right. If = B cm, B filed is D/50 T, v=B/5 m/s and R=A. (a) Explain and determine the current I? (5 points) (b) determine the magnitude of the required force. (5 points) (c) What external power is needed to move the rod? (5 points) 5. A C number of loop square coil of wire, with side length B/5 cm and total resistance CQ, is positioned perpendicular to a uniform D/100 T magnetic field. It is quickly pulled from the field at constant speed (moving perpendicular to B) to a region where B drops abruptly to zero. At t = 0, the right edge of the coil is at the edge of the field. It takes B/50 s for the whole coil to reach the field-free region. Find (a) the rate of change in flux through the coil (5 points) (b) the emf and current induced. (5 points) (c) How much energy is dissipated in the coil? ((5 points) (d) What was the average force required (Fext)? (5 points) x x XXXXX XXXXXXXX XXXX xx B=0 F ext 6. When unpolarized light is incident on a sheet of polarizing material with a transmission axis oriented vertically, what percentage of the light is transmitted through the material? (10 points)
