the question says, a single rectangular loop of wire with thedimentsions show in feg below is situated so that part is inside aregion of uniform magnetic field of .450T and part is outside thefield. The total resistance of the loop is .230 ohms, the force Fus used to pull the loop form the field at a constant velocity of3.40 m/s neglect gravity
