Task 31123.
The figure shows the cross-section of three straight infinitely long conductors with currents. Distance AB = BC = 5 cm, the currents I1 = I2 = 10 A and I3 = 20 A. Find: point on the straight line AC, in which the magnetic induction field produced by the currents is equal to zero, if the currents flow in the same direction.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
