Problem 3: The loop of wire shown in the figure below forms a right triangle and carries a current I = 5 A in the direction shown. The loop is in a uniform magnetic field that has magnitude B = 3T and the same direction as the current in side PQ of the loop. What is the net magnetic force on the loop? Answer: FB = ((0 + 12 − 12)N)✩ = 0. B 0.600 m P R -0.800 m
