As shown in the figure, a straight conductor parallel to the "x" axis can slide without friction on the top of two horizontal conducting rails which are parallel to the "y" axis, and at a distance of L = 0.2 m apart, in a magnetic field of magnitude B = 1.5 T and direction -z. A current I = 20 A flows through the conductor in the direction shown. A string is tied exactly at the center of the conductor, passes over a frictionless pulley, having tied at the other end a mass " m " which is suspended vertically. a) Draw the free body diagram of the conductor b) Calculate the magnetic force vector on the conductor c) If the driver is at rest, calculate the mass m in grams

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. (i) The rod is of length d = 1.00 m and mass m = 0.600 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 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 its passengers ride. The electromagnetic force on the axle will provide the motion of the car at the beginning of the roller-coaster ride. Your supervisor wants to test the substructure in the figure in a flat outdoor area on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height h = 2.20 m, the projection speed can be determined from how far from the ends of the rails the rod hits the ground. Your supervisor asks you to determine the length of the outdoor area needed to test the device. (Determine the total horizontal distance, in m, from the initial position of the rod on the tracks to the final position of the rod where it lands on the ground.) m

The circuit shown in the figure is used to make a magnetic balance to weigh objects. The mass m to be measured is hung from the center of the bar, that is in a uniform magnetic field of 1.50 T, directed into the plane of the figure. The battery voltage can be adjusted to vary the current in the circuit. The horizontal bar is 60.0 cm long and is made of extremely light-weight material. It is connected to the battery by thin vertical wires that can support no appreciable tension; all the weight of the suspended mass m is supported by the magnetic force on the bar. A resistor with R = 5.00 Ω is in series with the bar; the resistance of the rest of the circuit is much less than this. (Figure 1) Figure 1 of 1 Part A Which point, a or b, should be the positive terminal of the battery? a b Submit Request Answer Part B If the maximum terminal voltage of the battery is 175 V, what is the greatest mass m that this instrument can measure?
