Faraday's Law

  • #1

Homework Statement


The loop in the figure is being pushed into the 0.20 T magnetic field at 50 m/s. The resistance of the loop is 0.10 ohm.


Homework Equations


I=E/R
E=|dmagnetic flux/dt|


The Attempt at a Solution


I don't know how to even start this problem all the examples give more information. I don't see what the velocity does for this problem or how to figure out the area since all they give is the width. Some help or how to approach would be much appriciated.

I can't see the picture yet, but I think I offer some tips.
The velocity is important as it tells you how much of the loop (and therefore area) is in the magnetic field. You get your "length" from that (it will be changing). You need that for the flux, which will be changing based on how much of the loop is in the field.

What do you have to find?
