2. [-/4 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTIC Consider the following figure. (a) A conducting loop in the shape of a square of edge length { = 0.440 m carries a current / = 9.80 A as in the figure above. Calculate the magnitude and direction of the magnetic field at the center of the square. magnitude HT direction ---Select--- (b) If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic field at the center? magnitude T direction ---Select---3. [-/2 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANO In the figure below, the current in the long, straight wire is Ij = 6.40 A and the wire lies in the plane of the rectangular loop, which carries a current 12 = 10.0 A. The dimensions in the figure are c = 0.100 m, a = 0.150 m, and f = 0.420 m. Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire. magnitude direction ---Select--- 12 - a4. [-/3 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A single-turn square loop of wire, 2.00 cm on each edge, carries a clockwise current of 0.210 A. The loop is inside a solenoid, with the plane of the loop perpendicular to the magnetic field of the solenoid. The solenoid has 30.0 turns/cm and carries a clockwise current of 15.0 A. (a) Find the force on each side of the loop. magnitude direction ---Select--- (b) Find the magnitude of the torque acting on the loop. N . m
