A wire carrying a current of 2.51 A is bent into the shape of a square loop of side length 5.62 cm and is placed in the xy-plane. What is the torque on the wire loop if there is a uniform magnetic field of 0.133 T pointing in the +z direction? What is the torque on the wire loop if the magnetic field instead points in the +x direction?
4. A thin wire carrying a current I is bent into a shape with a central circular portion of radius R centered at the origin, and with two semi-infinite arms that extend to ro, as shown in the figure below. Find the direction and the magnitude of the magnetic field B at the center. y R I
Chapter 28, Problem 042 The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.78 m long and makes an angle of θ=42.1° with the x axis, and the wire carries a current of 1.21 A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field is given by (a)3.91 kT? (b)3.75 İ T?
Imagine that you have a metal wire bent into the shape of an equilateral triangle with side lengths of l. This triangle is carrying current, 1, in a direction clockwise around the triangle. Find the magnetic field (magnitude and direction) that the current produces at the center of the triangle. Hint: Use the Biot-Savart law to find the magnetic field for a finite straight wire. How does this help? -

[12] 13. A piece of wire is bent in the shape shown (two 550 cm horizontal section and a semi circle section with radius 285 cm). Determine the magnetic field (magnitude and direction) at point P, the center of the semicircle. The current/- 19.5 mA. (Hint you need Biot-Savart Law.) If you show your work in an organized and clear manner
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) Sketch a graph of the magnetic flux with respect to time. flux time (b)Is the direction of the induced current in the circular wire...

A very long wire carrying current I is bent into the shape shown in the diagram. Apply the general result obtained in class from the Biot-Savart Law, B = mu_0I/4pi r(cos theta_1 - cos theta_2), to find the net magnetic field B, magnitude and direction, at point P. Show all your work in detail: very specifically show what are theta_1 and theta_2 for each segment of the wire. Simplify the answer. Use extra pages if needed.
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!
