in the following figure, the bar moving at 16 ay m/s

In the following figure, the bar is moving at 16 a_y m/s and B = 12e^-2t a_z Wb/m^2. What is the voltage induced across the resistor at t=0^+ ?

Solution

At t=0⁺ Velocity of bar V= 16 a_y m/sec

B(t=0⁺}=12*e^-2*t=12*e^-2*0=12 Wb.m2

Length of Bar L=10 Cm=0.1 m

Induce EMF |E|= B*L*V=12*0.1*16=19.2 V

|E|=19.2 V
