The strength of the magnetic field created by a current-carrying wire found experimentally is B=?0I2?r where r is the distance from the wire, I is the current, and ?₀=4?10^-7 Tm/A is a constant. (From Unit 14 Reading.) Consider two parallel, current-carrying wires, as in the figure to the right. One wire carries 5.00 A of current into the page. The other carries 3.00 A of current out of the page.

- Determine the magnitude and direction of the net magnetic field at point P. Show your work and explain your reasoning.

- If a compass were placed at point P, what direction would it point? Explain.
