The unit of magnetic flux is named for Wilhelm Weber. A practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. Along with their individual accomplishments, Weber and Gauss built a telegraph in 1833 that consisted of a battery and switch, at one end of a transmission line 3 km long, operating an electromagnet at the other end. Suppose their transmission line was as diagrammed in the figure below. Two long, parallel wires, each having a mass per unit length of 45.5 g/m, are supported in a horizontal plane by strings ℓ = 6.15 cm long. When both wires carry the same current I, the wires repel each other so that the angle between the supporting strings is θ = 16.4°.

Three questions. Thanks 1. One long wire carries current 12.0 A to the left along the x axis. A second long wire carries current 80.0 A to the right along the line (y = 0.280 m, z = 0). (a) Where in the plane of the two wires is the total magnetic field equal to zero? (b) A particle with a charge of −2.00 µC is moving with a velocity of 150î Mm/s along the line (y = 0.100 m,...
