Transcribed Image Text:13.34. In Fig. 13-21 a radial conductor, 3 ≤ r ≤ 6 cm, is shown embedded in a rotating glass disk. Two 11.2 m2 resistors
complete two circuits. The disk turns at 12 rev/min. If the field at the disk is B = 0.30a, (T), calculate the electric
power generated. What is the effect of this on the rotation? Discuss Lenz's law as it applies to this problem.
