QUESTION 10 10 points Save Answer A segment of wire carries a current of 18 A along the X axis from X = 3.5 m to X = 0 and then along the y axis from y = 0 to y = -5.0 m. In this region of space, the magnetic eld is equal to 38 mT in the positive X direction. What is the direction and magnitude of the force on this segment of wire? QUESTION 6 The switch in the gure is closed at t= 0 when the current I is zero. What is the time when I = 50 mA? . K I 1 -., .140 T 401.1: Wu The figure shows a cross section of two parallel wires I1 = 6.2 A out of the paper and 12 = 2.8 A out of the paper. If distance d = 7.0 cm, how far from I1 is the position where net magnetic field B = 0? d O I1 12QUESTION 8 10 points Save Answer An AC generator consists of 58 turns of wire. Each turn has an area of 0.040 m2. The loop rotates in a uniform eld (B = 0.20 T) at a constant frequency of 60 Hz. What is the maximum induced emf? QUESTION 9 10 points Save Answer What is the magnitude of the magnetic force on a charged particle (Q = 7.0 yC) moving with a speed of 90 km/s in the positive X direction at a point where Bx = 3.0 T7 By = 5.0 T, and B; = 4.0 T
