Question

Problem 2. A wire carries a 7.00-A current along the x axis, and another wire carries a 6.00-A current
along the y axis, as shown in figure below. The point P is located at x = 4.00 m, y = 3.00 m.
(a) What is the magnetic field at point P, due to the vertical wire? Write your answer in unit-vector
notation.
(b) Find the magnetic field at point P, due to the horizontal wire. Write your answer in unit-vector
notation.
(c) Calculate the net magnetic field at point P. Write your answer in unit-vector notation.

**Problem 2.** A wire carries a 7.00-A current along the x-axis, and another wire carries a 6.00-A current along the y-axis, as shown in the figure below. The point P is located at \( x = 4.00 \, \text{m}, \, y = 3.00 \, \text{m} \).

(a) What is the magnetic field at point P, due to the vertical wire? Write your answer in unit-vector notation.

(b) Find the magnetic field at point P, due to the horizontal wire. Write your answer in unit-vector notation.

(c) Calculate the net magnetic field at point P. Write your answer in unit-vector notation.

**Diagram Explanation:**

The diagram shows two perpendicular wires placed along the x and y axes. The wire along the x-axis carries a current of 7.00 A in the positive x-direction, while the wire along the y-axis carries a current of 6.00 A in the positive y-direction. The point P, where the magnetic fields are to be calculated, is located at coordinates (4.00 m, 3.00 m). The diagram also uses arrows to indicate the direction of the currents in the wires.
