Two long, straight wiros carry currents in the directions shown in the figure above. I1 = 2A 12=9 A. a=8 cm, b=2 cm. a) Find the magnetic field strength at point P. B-( bị What force would 1 m of a third wire, carry a 6-A current out of the page, experience if place at P? F-( i+ J)N A long straight wire and a rectangular locp le in the same plane, as shown in the the figure above, where i1 7A, 12-3 A, a-20 cm, b- 25 cm, e 30 cm. Find the net force on the loop due to the long wire. (1.16 10A-5) N (positive if to the right) Hint: Force on top side and force on bottom side cancel out.
