Step 1
We know that the magnetic field due to a straight wire carrying current I at a distance r from the wire is given by the formula: B = (Ī¼ā * I) / (2 * Ļ * r), where Ī¼ā is the permeability of free space (4Ļ Ć 10ā»ā· Tm/A). Show moreā¦

Two infinitely long, parallel wires carry currents I1 = 10 A, which is directed into the page at coordinates (1, 1) cm, and I2 = 20 A, which is directed out of the page at (1, -1) cm. Use Ampere's Law to determine: (a) The magnitude and direction of the resultant magnetic field at the point P with coordinates (0, 1) cm, as shown. [2 x 10^-4 T, 143Ā°] (b) The magnitude and direction of the resultant magnetic force per unit length exerted on a third identical wire, that is parallel to both wires, carrying current I3 = 5 A that is directed out of the page through another point with coordinates (2, 0) cm. [1.58 x 10^-3 N/m, 252Ā°]
