3. DETAILS MY NOTES You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 15.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude 8 = 1.90 T. The electromagnetic force on the rod is parallel to the rails, causing the rod to roll to the right in the figure. When a full-scale device is produced, this rod will represent the axle of wheels on which the car and i on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height h = 1.80 m, the projection speed can be determined from how far from the ends of the rails the rod hits the ground. Your…

Consider a 150 turn square loop of wire 15.5 cm on a side that carries a 56 A current in a 1.6 T field. What is the maximum torque on the loop of wire in N⋅m? What is the magnitude of the torque in N⋅m when the angle between the field and the normal to the plane of the loop θ is 14°? 3. Consider two two long, straight, parallel, current-carrying wires, separated by a distance d = 4.5 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. If both wires are carrying a current of 3.5 A, what is the magnitude of the magnetic field, in teslas, at point P? If the current from the left wire is 3.5 A…

1. Here let's analyze the demo from lecture with two parallel wires. a) We will start with the case that the currents IR and IL are in the same direction: e IL IR d If the length of the wires is much greater than the distance between the wires (l >> d), find an approximate expression for the magnetic force on each wire. Are the forces attractive or repulsive? b) What would happen to the direction of the forces if you switched the direction of IR or IL? Make sure to explain your answer.
