3.1. Two metallic rods of length L = 40 cm and unknown linear mass density 1 are suspended from a support using lightweight strings of length s = 8 cm, as shown in the diagram (a) below. The rods are then connected to a circuit in such a way that same current / = 20 A passes through both rods, but flows in opposite directions. When connected in such a way, the rods move away from each other and at...
Two metallic rods of length 40 cm and unknown linear mass density are suspended from a support using lightweight strings of length 8 cm. The rods are then connected to a circuit in such a way that same current 20 A passes through both rods, but flows in opposite directions. When connected in such a way, the rods move away from each other and at equilibrium are separated by a distance 2 cm. What is the linear mass density of the...
Two conducting cylindrical wires with a diameter of 3 cm and length of 40 cm are made from a metal with a density of 2710 kg/m'. The wires carry equal but opposite current (the direction given in the diagram) of 7.5 amps and are suspended from a thread of length 25 cm and are 12 cm apart from each other. An external uniform magnetic field of magnitude 3.0 Tesla is applied to the system. A) Calculate the net magnetic field...
In the figure, a rectangular loop of wire with length a = 3.8 cm, width b = 1.3 cm, and resistance R = 0.71 m? is placed near an infinitely long wire carrying current i = 6.7 A. The loop is then moved away from the wire at a constant speed v = 4.8 mm/s. When the center of the loop is at distance r = 2.8 cm, what are (a) the magnitude of the magnetic flux through the loop...
A wire with a linear mass density of 1.17 g/cm moves at a constant speed on a horizontal surface and the coefficient of kinetic friction between the wire and the surface is 0.250. If the wire carries a current of 1.39 A westward and moves horizontally to the south, determine the magnitude and direction of the smallest magnetic field that can accomplish this. magnitude direction ---Select- As shown in the figure, a conducting rod with a linear mass density of...
Two parallel rods are each 0.39 m in length. They are attached at their centers to a spring that is initially neither stretched nor compressed. The spring has a spring constant of 220 N/m. When 1200 A of current is in each rod in the same direction, the spring is observed to be compressed by 2.7 cm. Treat the rods as long, straight wires and find the separation between them when the current is present. Number i Units The x,...

In the figure, a rectangular loop of wire with length a = 3.8 cm, width b = 2.2 cm, and resistance R = 0.70 mΩ is placed near an infinitely long wire carrying current I = 4.7 A. The loop is then moved away from the wire at a constant speed v = 3.9 mm/s, when the center of the loop is at distance r = 7.9 cm, what are (a) the magnitude of the magnetic flux through the loop...
A segment of wire has a radius R= 27 mm and length L = 39 cm that carries a uniform current density J = 470 A/m2. What is the current i, flowing through a circular loop of radius r = 18.5 mm offset from the central axis of the wire by d = 3.5 mm? Express your answer using one decimal place. You answer should be in mA.
Please answer it ASAP thanks In the figure, a rectangular loop of wire with length a = 2.9 cm, width b = 1.1 cm, and resistance R = 0.27 m ohm is placed near an infinitely long wire carrying current i = 4.6 A. The loop is then moved away from the wire at a constant speed v = 5.8 mm/s. When the center of the loop is at distance r = 2.3 cm, what are (a) the magnitude of...
