Question

Question 11 5 pts A rotating generator has a square planar coil consisting of 100 turns. The coil rotates 60 times per second in a magnetic field of 1.25T and yields a peak output voltage of 300 V. What is the length of one side of the coll? O 0.64 cm 8.0 cm O 64 cm O 80 cm O 120 cm Question 12 5 pts The figure shows a stationary conducting loop adjacent to a vertical current-carrying wire. For which of the following conditions will a counter-clockwise induced current circulate in the stationary loop? Current-carrying wire Stationary conducting loop 612 30 W

Answer 1

a solution: N = 100 tundi Speak = 3оо у na 60 rbs B = 1,25 Area = axa axa = a a? now, we know formula for peak voltage of generator. IE pearl = NABW wa 2 Kn 27 (80) so, using above formula >) 300 300 - (100) Ca?) (1-25) (2 160) - (100)(1.25) (2700) 2 a 300 a a 0.0063694 . a a = 0.08. m length of one side of coil = 18 un 8 cm so,
