Problem 6: Consider two current-carrying wires, separated by a distance d = 3.1 cm, as shown in the figure. The left wire is directed out of the page with current I1, and the right wire is directed into the page with current I2. The point P is a distance d from both wires, so the wires and the point form an equilateral triangle.
Part (a) If both wires are carrying a current of 8.5 A, what is the magnitude of the magnetic field, in tesla, at point P?
B = ( ( ( 4 * 10^(-7) ) ( 8.5 ) ) / ( ( 2 ) ( 3.1 * 10^(-2) ) ) ) ( sin( 30 ) + sin( 30 ) )
B = 5.484E-5
Part (b) If the current from the first wire is 8.5 A and the current from the second is 13 A, what is the magnitude of the magnetic field, in tesla, at point P?
