3. Two wires are carrying currents in the same direction as shown in the diagram below. The two wires are 25 cm apart. The first wire carries a current of 2 A and the second wire carries a current of 3 A. Both wires are 5 m long. I2 a. What is the direction of the magnetic field created by the first wire at the position where the second wire is located? Draw the vector. b. What is the direction of the magnetic field created by the second wire at the position where the first wire is located? Draw the vector. c. What is the direction of the magnetic force that is acting on the second wire due to the first wire's magnetic field? Draw the vector.

Pr2. A very long, straight current-carrying wire is bent at the middle two different ways, so that it takes the shapes depicted in figures a) and b). Find the direction and magnitude of the magnetic field in both cases at the center C of the semicircle (of radius R = 10 cm), if the current flowing in the wire is I = 2 A. a) b) С.

1. In the diagram below, a charged particle enters a region of uniform magnètic field where B 0.6 T. The particle has an initial speed of 2.7 x 106 m/s. Keep in mind Newton's Second Law and recall the equation for centripetal acceleration: 1²/r. a. Ignore gravity and first determine the sign of the charged particle if it follows the trajectory of the dashed semicircle. b. Next, use the information given to derive an equation for the charge-to-mass ratio (q/m) of the particle in terms of the particle's speed, the magnitude of the magnetic field and the radius of the semicircle. c. Lastly, calculate the charge to mass ratio of this particle. 95.0 cm B

Consider the current-carrying wire shown in the figure. The current creates a magnetic field at the point P, which is the center of the arc segment of the wire. If 0 = 30.0°, the radius of the arc is 0.800 m, and the current is 5.00 A, what are the magnitude (in nT) and direction of the field produced at P? magnitude 3.272*10**-7X Did you forget to convert from T to nT? nT
