Φ B = xHB 2 + ( D x ) HB 1 = DHB 1 + xH ( B 2 B 1 ) which means d Φ B dt = dx dt H ( B 2 B 1 ) = vH ( B 2 B 1 ) i = vH ( B 2 B 1 )/ R . Similar considerations hold (replacing “ B 1 ” with 0 and B 2 ” with B 1 ) for the loop crossing initially from the zero-field region (to the left of Fig. 30-81(a)) into region 1. (a) In this latter case, appeal to Fig. 30-81(b) leads to 3.0 × 10 6 A = (0.40 m/s)(0.015 m) B 1 /(0.020 ) which yields B 1 = 10 µ T. (b) Lenz’s law considerations lead us to conclude that the direction of the region 1 field is
