Question

13. Three current-carrying wires with a length of 2 m each are placed in the plane of the page parallel to each other. The distances between the wires are given in the figure. The currents running in the wires are all equal 00 A, the directions of the currents are marked in the figure by arrows. Find the absolute value and the ?? direction of the magnetic force acting on the middle wire. 5cm 10cm 14. A current l 500 A is running along a straight wire. A square loop is positioned at a distance r 10 crm the wire. A current 1 300 A is running in the loop. The straight wire and the loop are both positioned in the plane of the associated figure by arrows. (a) What is the magnitude of the net magnetic force acting on the loop? (b) Do the wire and the loop repel or attract each other? Explain why (Ans. Fi-0.03 N, F 0.015 N, F- 0.015 N, repel) page, two sides of the loop are parallel to the wire. The directions of the currents are shown in the The length of each side of the loop is a 10 cm. 15. A current of 0.2 A is running in a solenoid of length 0.1 m. Find the number of turns in the solenoid if the magnetic field inside the solenoid is 0.01 T. (Answer 3979 turns)
