Since there is no symmetry of Amperian loop for location ''P'', the Ampere's law is not suitable to use.
Biot-Savart law can be applied with symmetrical current elements along the circumference to find the magnetic field at ''P''
Answer (b). Biot-Savart Law
5. Given a loop of wire carrying a currentl (shown to the right), which of the...
Which of the following is false about a wire carrying current to the right? a. Comparing how the wire looks when viewed from in front of the page or from behind the page and considering what one expects if the current changes direction shows that the radial component of the magnetic field must be zero. b. Since the field must be perpendicular to the current, the component of field parallel to the wire must be zero. c. Application of Ampere’s...
Consider the current-carrying wire shown in the figure. The current creates a magnetic field at the point P, which is the center of the arc segment of the wire. If 0 = 20.0°, the radius of the arc is 0.700 m, and the current is 2.00 A, what are the magnitude (in nT) and direction of the field produced at P? P i magnitude 285.7 Apply the Biot-Savart law. What will be the contributions of the segments of wire along...
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.

The field is directed out of the page. The field is directed to the right. The field is directed to the left....
Use the Biot-Savart law to set up but don't solve the equation(s)/integral(s) that could be solved to give the magnetic field intensity H at point P that is caused by the current-carrying wire segments shown.
An infinitely long conductor carrying current is bent at a right angle as shown in Figure 1. Point Pis located a distance b from the corner of the wire. Only one section of this current contributes to the magnetic field at pt. P. Why? The general formula (derived from the Biot-Savart Law) for the magnitude of the magnetic field a distance a away from a thin, straight conductor is: B = f (sin 8, - sin 02) For this problem,...
3. (a) Use Biot-Savart Law to find the magnetic field of wire, along the z-axis, carrying a current I (in direction), at a point P a distance r from the wire. Do this for both a finite wire (21 <2<z2), and an infinite wire (-0<z< too). (6) Use the result of part (a) to evaluate the net magnetic field of the wires shown at point P (0,0,2).
