11. Which of the following ja not a coarreet sepresautation of 1 and ? te: 12. (6 pts) A long solid cylindrical conductor oriented along the axis bos radios aud Jz. Use the integral form of Ampere's Lavw to finsd the magnetic field R. Shoow your aj Find H for caames b) Find for r > a 13. (9 pts) A long straight wire carries a constant current I in the 7-dinoction. A nearby lap in the ve plae carries a constant current l2 in the clockwise direction as shown. B, is the magnetic flux density due to the straight wire. ai The direction of Bi at the location of the loop is: (i) i (i)-x (iii) y tiv) (v) 2 b) The net force on the loop is not zero because: 12 (vi)-k 0j the force is stronger on the sides of the loop perpendicular to the wire () the net force on the loop is zero, though the torque is not zero Giij the iorce is stronger on the side of the loop closer to the wire (ivj the force is stronger on the side of the loop farhest away from the wire c) The direction of the net force on the loop is: (ii v)(vi)4 If yes, calculats the terque d) ls there a net torque on the loop? Yes or No If so, explain why aot.Explanation / Answer
11a)
According to the Right Hand Rule,
If the curl of the hand shows the direction of electric current the thumb points in direction of H.
In first figure the current is flowing in downward direction so according to right hand rule the direction of right hand curl denotes the direction of field and according to the curent in figure the field should be clockwise but the field shown in figure is anticlockwise so this not a corect combination of I and H
