A wire bent into the shape of a semicircle of radius Rforms a closed circuit and carries a current I. The circuit lies in the xy plane, and a uniform magnetic field is present along the positive y axis as in Figure 29.12. Find the magnetic force on the straight portion of the wire and on the curved portion. Please answer the part I circled in red!!! Thank you!

07. A rigid wire, carrying a current I, consists of semicircle of radius R and two straight portions as shown in the following figure. The wire lies in a plane perpendicular to a uniform magnetic field B. Note choice of x and y axis. The straight portions each have length 1 within the field. Determine the net force on the wire due to the magnetic field. (8 Marks)
The figure shows a wire with a semicircle of radius 5 cm in between two wires each of length 5 cm. A current of 5 A flows in the direction as shown. a. What is the magnitude and direction of the magnetic field at the center of the semicircle? b. Do the straight segments of the wire contribute to the magnetic field? Explain. c. If another segment of wire exactly the same as the wire in the first problem is...
A current is set up in a wire loop consisting of a semicircle of radius 4.52 cm, a smaller concentric semicircle, and two radial straight lengths, all in the same plane. Part (a) of the figure shows the arrangement but is not drawn to scale. The magnitude of the magnetic field produced at the center of curvature is 47.19 T. The smaller semicircle is then flipped over (rotated) until the loop is again entirely in the same plane (part (b)...

The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.0 m long and makes an angle of θ = 60° with the x axis, and the wire carries a current of 2.0 A. What is the magnitude of the magnetic force on the wire in unit-vector notation if the magnetic field is given by (a) 4.0 k T and (b) 4.0 iT?
2) A straight wire is partially bent into the shape of a circle as shown below. A uniform magnetic field is directed perpendicular to the plane of the circle and into the page. Each end of the wire is then pulled at a constant speed so that the area of the circle shrinks to zero.

A wire 90.0 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 35.0 mm , y = 0, and then in another straight line from x = 35.0 mm , y = 0 to x = 35.0 mm , y = 55.0 mm . The wire is in an external uniform 0.700-T magnetic field in the +z direction, and the current through the wire...
