current in a wire?? 1. The problem statement, all variables and given/known data A long, straight wire carries a current of I_1 = 20 A as shown below. A rectangular coil with two sides parallel to the straight wire has sides 5 cm and 10 cm with the near side a distance 2 cm from the wire. The coil carries a current of I_2 = 4 A. PIC IS ATTACHED! Find the force on each segment of the rectangular coil due to the current in the long, straight wire. i found all but right and net (if i find right i can get net) top 2.0044e-5 N left 8e-5 N right bottom 2.0044e-5 N net i used ((I_2 * Uo* I_1 ) / 2pi ) * ln(7/2) i know that the force will be pointing left but dont know its magnitude? does anyone know how this works and if so can you help me through the problem? thanks!!
