A conducting square loop (L × L) moving with velocity vo ay m/s where the magnetic flux density is B=Bo ax Wb/m2 in 0 < y < 2L, and is equal to zero when 0 > y and y > L. Determine the current in the loop and plot its magnitude as a function in the loop's position in the y-axis. Assume the loop's front at y=0 and t=0 (time), and its resistance is R Ω.
I=V/R (Ohm's law)
Vemf=u × B × dl (× refers to cross product, u is the velocity)
The Attempt at a Solution
Vemf=- vo B l V
I=Vemf/R = ( - vo B l )/ R A
I don't know whether I am doing OK or not. I feel like I've missed up with dl. Can anyone clarify?
