The problem states: A loop of area 4cm^2 has its plane parallel to the field lines of the magnetic field, B = 0.6t, as shown in the figure. The loop is pulled in the opposite direction of the field with a constant velocity of v = 6m/s. I am confused as to solve this because I can't figure out an equation to use. It gives me area, magnetic filed, and velocity for a loop in plane. I can't use V=NB dA/dt sin q because I don't know t and I can't use V=NBLv because I don't know L. No matter how I try to solve for either of those values I get no where. I'm stuck and don't know how to start.
