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.
Part B (Advanced) The figure below shows a long straight wire (Wire 1) carrying a constant current, I. A second wire (Wire 2), carrying a constant current, 12, is placed near the first wire with dimensions as shown (a) Discuss the direction of the force that each segment of Wire 2 experiences due to the field (b) Calculate an expression for the net force on Wire 2 due to the field of Wire 1. Note that Appendix A of Knight...
4. (a) A long straight wire carrying a current is placed near
a current-carrying rectangular loop. Describe how, and why, the
loop would move as a result of the magnetic forces from the long
wire. The current in the loop is counterclockwise.
(b) Suppose that you were to put in a different
loop below the long wire (and still in the plane of the page).
Draw the shape of a loop that would...

Р [12]35. A piece of wire is bent in the shape shown (two 32.6 cm straight sections and a 3/4 of a circle section with radius r - 320 cm). Based on this information 17.4 m which of the following is true? Note that point P is the center of the 3/4th circular section. Circle the TRUE statement(s). Statements: (a) The magnetic field at point P is due only to the current in the two straight sections. (b) The law...
Sinusoid Shaped Wire A wire segment is bent into a sinusoidal shape with period of 2T, which gives y sin(x) and the wire has length of 2 π in the x-direction. The wire is carrying a current of 3.5 Amps in the direction shown in the figure. There is a magnetic field in the vicinity of the wire which points in the positive z-direction with a magnitude given by B-Bor, where Bo = 17.50 T/m, what is the y-component of...
[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
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
A thick uniform wire is bent into the shape of the letter "U" as shown on the right. Which point indicates the location of the center of mass of this wire?
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? -
