A conducting wire frame with side lengths a and b lies at rest on a frictionless horizontal

Question:

A conducting wire frame with side lengths a and b lies at rest on a frictionless horizontal surface at a distance l from a long straight wire carrying a current I₀ (see figure below). The mass of the frame is m, and its total resistance is R. Use an impulse approximation to find the magnitude and the direction of the velocity of the frame after the current in the long straight wire has been abruptly switched off.
