4. A rectangular 12.0 cm by 36.0 cm circuit carrying a 5.50A current is placed in area with uniform magnetic field of .800 T. The rectangular is oriented with its long side parallel to magnetic field. A) Find the magnitude and the direction of the magnetic force on each side of this circuit. Illustrate your answer with the clear diagram of the current and forces. B) Find the magnitude of the net force on the entire circuit. (10 points) 5. The magnetic field on the distance 3.2 cm from the current - carrying straight, long conductor is 2.5x 1071". How large is the current? On a diagram show direction of the current, and direction of the magnetic field lines (10points)
