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. Wire 1 carries 2.00 A of current into the screen. Wire 2 carries 5.00 A of current out of the screen. The wires are 0.05 m apart.

A.) Draw a vector representing the direction of the net magnetic field at point P. Explain why you drew it the way you did.

B.) Calculate the magnitude of the net magnetic field at point P. Show your work.
