= Three wires, bundled together, carry currents I₁ = 4.0 A, 12 = 3.0 A, and I3 10.0 A respectively. The currents I₁ and I2 are directed out of the page, and the current 13 is directed into the page. Calculate B, the magnitude of the magnetic field, at a dis- tance of 0.05 m from the bundle of wires. Sketch the magnetic field at 0.05 m from the bundle, indicating the direction of the field.
