Document Summary

9:36 am: motional emf page 1, motional emf page 2, moving coil. At t=0, a rectangular coil of resistance r = 2 ohms and dimensions w = 3 cm and l = 8 cm enters a region of constant magnetic field b = 1. 6 t directed into the screen as shown. The length of the region containing the magnetic field is lb = 15 cm. The coil is observed to move at constant velocity v = 5 cm/s. What is the force required at time t = 0. 8 sec to maintain this velocity: motional emf page 3, conducting loop moving through a constant magnetic. A conducting loop is made in the form of two squares of sides s1 = 3. 3cm and s2 = 5. 4 cm as shown. At time t = 0, the loop enters a region of length l = 17 cm that contains a uniform magnetic field b. = 1 t, directed in the positive z-direction.
