Consider the system pictured in the figure below. A 15.9-cm horizontal wire of mass 14.3 g is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. The wire is free to move vertically without friction on the two vertical conductors. When a 4.75-A...

(Magnetic Force on a Wire) A horizontal,
current-carrying wire of mass m = 40.0 g is free to slide without
friction along two vertical conducting rails spaced l = 80.0 cm
apart as in Figure. A uniform magnetic field of B = 1.20 T is
directed into the plane of the drawing. What magnitude and

21. Concept 26-7 gives the magnetic torque on a current loop with a single turn of wire. To achieve higher torques suitable for practical applications, motors use coils of wire with several turns. What is the maximum torque on a coil with 100 turns, area 9.0 × 10-4 m2, and current 2.0 A in the presence of a magnetic field of magnitude 0.2 T? Express your answer in N·m. . 24.

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...

A 2.5 cm-long horizontal wire segment has mass 0.15 g and carries a current sufficiently large that it levitates when the segment is in a region of B field upward with magnitude 1.5 T. The current is passed to the segment that is in the magnetic field by way of massless electrical leads. What is the magnitude of the current that the wire carries?

4. Consider a circular loop of wire with a mass m and a radius R. The circular loop is vertical such that gravitational force on the loop points straight down. You may assume this is near the surface of the earth such that the force of gravity has a magnitude FGl mg. The upper half of the circular wire is immersed in a uniform magnetic field B pointing into the page. In the figure below this corresponds to the region...
