Question

1. Two very long wires run in the z direction, one at (1,0 cm, the other at (-1,0) cm. (a) If both wires are carrying a positive current of 0.6 A upwards in z, calculate the magnetic field strength at the origin. Remember that magnetic fields add like vectors. (b) Do the same problem, bt wth the wire at (-1,0) cm carrying 0.6 A downwards
