## Homework Statement

Hello all, not really sure what to title this. Heres the question:

Ceicil sets a trap. According to ceicil, all she has to do is somehow attach a conductive bar with resistance 1Ω to the turkey and then get it to walk along a wire loop in a region of 100T magnetic field (as shown in turkeyforce.jpg). Ceicil estimates that the turkey will be walking at 1.00m/s. How much force would the turkey need to exert on the bar to be able to continue at this speed?

## Homework Equations

Lets call the dimensions of the box (that the turkey's bar) l for "y-component" and x for x component. The "y" component is actually given to us in the problem (2m).

ε=##\frac{-dΦb}{dt}##= ##\frac{-BdA}{dt}##=##\frac{-Bdlx}{dt}##=##\frac{-Bldx}{dt}##=-Blv

F=ILxB

ΔV=IR

## The Attempt at a Solution

If you push to the right (or in our case the turkey runs to the right at a given velocity) the turkey will experience a force in the opposite direction

I=##\frac{Blv}{R}##

F=##\frac{Blvlb}{R}##=##\frac{B^2l^2v}{R}##

As we can see the amount of "x" the turkey goes does not affect our problem. (is this because there is a uniform magnetic field?)

F=##\frac{100T^22m^21m/s^2}{1Ω}##=4*10^4N?

Not completely solid with these topics... how does this look?
