3.) The current distribution below shows the cross-section of a solenoid and two infinite wires oriented along the z-direction (+z: out of page, -z: in to page). Wire 1 has a current of 40 A, Wire 2 has a current of 30 A, and the solenoid has a current of 20 A. a. Determine the magnitude and direction (unit vector) of the magnetic field at the origin produced by i. The solenoid ii. Wire 1 iii. Wire 2 b. Determine the net magnetic field at the origin. c. Determine the angle of the net magnetic field at the origin with respect to the x-axis. y B = MonL X 2 = N/ L ON = 8 Wire 1 D, = 2.0 mm Wire 2 X D2= 3.0 mm
