## Homework Statement

A conducting square loop (L × L) moving with velocity

**v**where the magnetic flux density is

_{o ay}m/s**B=B**in

_{o ax}Wb/m^{2}**0**, and is equal to zero when

__<__y__<__2L**0**. 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 and y > L**y=0**and

**t=0**(time), and its resistance is

**R Ω**.

## Homework Equations

I=V/R (Ohm's law)

V

_{emf}=u × B × dl (

**×**refers to cross product,

**u**is the velocity)

## The Attempt at a Solution

V

_{emf}=- v

_{o}B l

**V**

I=V

_{emf}/R = ( - v

_{o}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?
