The unit of magnetic flux is named for Wilhelm Weber. The practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. Both were scientists at Gottingen, Germany. In addition to their individual accomplishments, they built a telegraph together in 1833. It consisted of a battery and switch that were positioned at one end of 3 transmission line 3 km long operating 3n electromagnet at the other end. (Andre Ampere suggested electrical signaling in 1821; Samuel Morse built a telegraph line between Baltimore 3nd Washington in 1844.) Suppose that Weber and Gauss's transmission line was aS diagrammed in Figure P30.18. Two long, parallel wires, each having a mass per unit length of 36.0 g/m, are supported in a horizontal plane by strings 6.00 cm long. Each wire carries the same current 7, causing the wires to repel each other so that the angle theta between the supporting strings of 16.0 degree . Are the currents in the same or in opposite directions? opposite same Find the magnitude of the current.
