# Evaluate the induced $emf$ in the loop if the wire carries a current of 50A and the loop has an instantaneous velocity $v = 10 m/s$ at the location $x= 0.2 m,$ as shown, Take $a = 0.1$ and assume that the loop has a large resistance.

$(a)0.5 \times 10^{-5} volts$
$(b) 5 \times 10^{-5} volts$
$(c) 50 \times 10^{-5} volts$
$(d) 0.05 \times 10^{-5} volts$
