An arbitrarily curved wire that carries a current between two endpoints in the presence of a uniform magnetic field will experience the same net magnetic force as a straight wire carrying the same current between the same endpoints. Essentially, any forces experienced by parts of the wire that curve or twist away from the straight-line path are canceled out by forces on sections that curve back toward the original path. Furthermore, if the wire forms a closed loop in between the endpoints, the net force on the closed loop is zero. Using this result, consider a town where the Earth's magnetic field has a magnitude of 51.3 μT. The magnetic field vector lies in a vertical plane defined by the north-south and up-down axes, and it points 60.0∘ below the northward direction. In this town, a storefront window lies along the north-south vertical plane, and in the window is a neon sign (which is a thin current-carrying discharge tube). The sign carries a 35.1 mA current, starting from the lower south corner of the window, and ending at the opposite corner, which is 1.32 m to the north and 0.850 m upward. The sign spells out the word "BURGERS" between the two points. What is the net vector magnetic force (in μN ) on the neon sign? (Take east to be the +x-axis, up to be the +y-axis, and south to be the +z-axis. Do not include units in your answer.) F→B = μN

A loop of wire carrying a current of 2.0 A is in the shape of a right triangle with two equal sides, each 15 cm long. A 0.7 T uniform magnetic field is in the plane of the triangle and is perpendicular to the hypotenuse. The resultant magnetic force on the two equal sides has a magnitude of: 0 N 0.21 N 0.30 N 0.41 N 0.51 N

Figure (a) shows an element of length ds = 1.24 μm in a very long straight wire carrying current. The current in that element sets up a differential magnetic field dB at points in the surrounding space. Figure (b) gives the magnitude dB of the field for points 5.6 cm from the element, as a function of angle θ between the wire and a straight line to the point. The vertical scale is set by dBs = 60.2 pT. What is the magnitude of the magnetic field set up by the entire wire at perpendicular distance 5.6 cm from the wire? Number Units
