A metal bar (length ( = 15 cm) is moving to the right at 120 m/s across a U-shaped conductor in a region where a uniform 17 ut field points in the direction shown. Assume that the bar and wires have no resistance and that R = 7.12. Zero-resistance wires R x(t) a. What is the induced current in the wire? Submit this answer below. b. Is this induced current clockwise or counterclockwise? Explain the process you used to determine...
Page 3 2) The circuit shown is used to make a balance to weigh objects. The bar is hung in a uniform magnetic field of 1.0 T, directed into the plane. The horizontal bar is 50 cm long and made of very light material. A resistor with R - 5.0 is in series with the bar. The resistance in the rest of the circuit is negligible. It is possible to adjust the voltage of the battery via a dial. The...
A small bar magnet (mass = 200 g, length = 15 cm) has a magnetic moment of 7.5 Am2. What is the maximum possible torque which could act on this magnet in a field of 5x10-5 T? A: 3.75x10^-4Nm
please help Problem 25.5 A 30 g horizontal metal bar, 13-cm-long, is free to slide up and down between two tall, vertical metal rods that are 13 cm apart. A 6.0x10-2 T magnetic field is directed perpendicular to the plane of the rods. The bar is raised to near the top of the rods, and a 1.0 12 resistor is connected across the two rods at the top. Then the bar is dropped. Part A What is the term Express...
A wire (mass = 55 g, length = 30 cm) is suspended horizontally by two vertical wires which conduct a current I = 5.0 A, as shown in the figure. The magnetic field in the region is into the paper and has a magnitude of 90 mT. What is the tension in either wire? I I
