Solving a problem in physics section 4 paragraph 16 ele

16. At frame length l = 10 cm and a diameter d = 5 cm is wound 150 turns of wire. Through the middle of the frame in the direction of one of its diameters extends copper conductor with a current I1 = 5A. Assuming the average magnetic field within a homogeneous part of the solenoid, determine the force with which it acts on the portion of the conductor inside the frame, when the current in the solenoid I2 = 1A.
