current in a wire??
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 2.0044e5 N
left 8e5 N
right
bottom 2.0044e5 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!!
