A single rectangular loop of wire with width w = 30.7 cm and length L = 79.7 cm is situated so that part is inside a region of uniform magnetic field of 0.407 T and part is outside the field. The total resistance of the loop is 0.244 Ω. Calculate the force F required to pull the loop from the field (to the right) at a constant velocity of 3.56 m/s. Neglect gravity.
HELP: What current is induced when the loop is pulled from the field? What is the magnetic force on the current-carrying wire of the loop?
The Attempt at a Solution
I found the emf to be ..448 (-1(0-(.407x.3985x.309))/.1119=.448)
From there I found the current to be 1.836 A and using that I found the Force to be .298
This is incorrect and I'm not quite sure what I'm doing wrong. The use of the velocity throws me off and I have a feeling my mistake is coming from there.
