3: (13% of Assignment Value) Two parallel wires are separated by a distance R as shown in the diagram. As compared to their separation, the wires are very long, extending well beyond the boundaries of the image. Wire 1 carries current I1. Wire 2 carries current I2 in the same direction as the first current. Coordinate axes have been included for convenience. - Part (a) What is the direction of the magnetic field due to current I1 at the location of Wire 2? into the page (-k) Correct! - Part (b) Enter an expression for the magnitude of the magnetic field due to the current I1 at the location of Wire 2. B1 = 0 I1/( 2 R ) Correct! - Part (c) What is the direction of a finite current element I2L2 of the second wire? towards the top of the page (+) Attempts Remain
