What is the strength of the motion and that induces an EMF of 0.251 mV across the rod? Express the answer in milliteslas. At this opportunity lar to your direction of tic field that is perpendicular to both the rod and your direction of Number 0708 mT There is a hint available! View the hint by clicking on the divider bar again to hide the hint on the boltom divider Close Previcus Check Answer Next HntExplanation / Answer
From faraday law of EM induction.
induced emf = B*L*v
Given data.
induced emf = 0.251 mV = 0.251 x 10^-3 V
L = 1.19 m
v = 3.05 m/s
Substitute values.
0.251 x 10^-3 = B x 1.19 x 3.05
B = 6.915 x 10^-5 T = 0.069 mT
